Project Title: GSM-Based Intrusion Detector System
Student: Acheampong Nana Archibold
Supervisor: Dr. Koudjo Mawuefam Koumadi
Abstract:
Restricted areas such as server rooms of companies, laboratories, offices, etc. require maximum security so as to be accessed only by authorized individuals. Our homes, garages, warehouses, etc. also need some form of protection from thieves and other unauthorized individuals. The incidence of false alarms in areas that employ alarm systems in detecting motion is also a major problem that needs consideration and solution. The GSM-Based Intrusion Detector System is a motion detector system that allows homes and other restricted areas to be kept against trespassing. It also allows the owner of the house or other facility to know the state of affairs in the facility whilst away.
The system is composed of three passive infrared sensors that detect motion. When these sensors detect motion, their output goes to a microcontroller, which checks the number of sensor outputs received. Upon reception of two or all three sensor outputs, the microcontroller causes a buzzer to sound an alarm, whilst lighting a Light Emitting Diode (LED) to signify the detection of motion. The microcontroller then triggers a GSM module to send an intrusion alert message to the user’s phone over the GSM network via Short Message Service (SMS).
Several tests carried out in the project employed single and multiple sensors at different instances to detect motion. The results of these tests revealed that the use of multiple sensors provided quick detection of motion. This was partly due to the large area that was covered when multiple sensors were employed, as compared to the area covered when only one sensor was used. The tests also revealed that the use of multiple sensors reduced the incidence of false intrusion detection notification.
GSM-Based Intrusion Detector System guarantees safety in the area under surveillance. It also provides authentic notification when intrusion is detected through its multisensory component, which minimizes false alarms to a considerable extent.
Project Title: GPS/GSM Based Vehicle Tracking &Alert System for Commercial Intercity Buses
Student: Fleischer Paul Benjamin Spurgeon
Atso Yao Nelson
Supervisor: Mr. Appah Bremang
Abstract:
GPS/GSM based Vehicle Tracking and Alert System is a tracking system which allows inter-city transport companies to track their vehicles in real-time and provides an alert system for reporting armed robbery and accident occurrences. In recent times, there have been a considerable number of accident and armed robbery cases on our inter-city roads in Ghana. Also, company administrators do not have real time information on their vehicles during the trip. GPS/GSM-based Vehicle Tracking and Alert System provide a screen display to inform passengers onboard of the towns the vehicle is approaching as well as company administrators. The Alert System sends notification to police and ambulance services as and when it is triggered. The evolutionary model was employed in the development of this system due to its incremental process which rightly suits the system.
This system operates on GPS (Global Positioning System) and GSM (Global System for Mobile Communications) technologies. An onboard unit which is made up of a combination of GPS module, a microcontroller and a GSM modem is embedded in the vehicle to be tracked. The GPS module receives position and speed information of the vehicle and transmits it to the microcontroller. The microcontroller then sends the processed information to the GSM modem which transmits it over the GSM network via SMS (Short Message Service). The microcontroller also processes alert information based on a trigger from the airbag circuitry or a panic button press by the driver. An LCD screen is also connected to the microcontroller and displays information on the towns the vehicle is approaching. The system provides a quick response to accidents and robbery cases, real-time position, speed information and changes in routes.
GPS/GSM Based Vehicle Tracking and Alert System guarantee some benefits to the corporation, the passenger and the driver. This system provides real-time information for better fleet management and better planning in the case of changes in route and information on accident and robbery trends. In future, a web-interface could be created to upload alert information to a central database for data mining.
Project Title: Design of an Antenna to Boost GSM Signal Reception
Student: Agbomadzie David Kwashie
Supervisor: Prof. Anthony N. Nzeako
Abstract:
The GSM signal Amplifier is designed to boost the weak GSM signal reception by cell phones in areas where the GSM services are impaired by signal attenuation by structural obstacles such within buildings and behind trees. It is a common for cell phone subscribers especially in rural areas to experience signal attenuation or no reception on their phone. The system designed is aimed at helping mobile users enjoy the full benefits of their subscription. This project is carried out using basic principle of wireless communication and signal attenuation. Firstly, the concept of wireless communication between the base station (BTS) and the mobile station was studied and the problem of signal attenuation analyzed. A further study was conducted on signal reception by an antenna and the fundamental principle of signal amplification. The understanding of VHF and UHF and their characteristics in a specific medium was helpful in the design of the system. The system is made up of three (3) main sections, the antenna, the amplifier and the transmitter. The amplifier is designed to both receive the weak GSM signal and as well as output an amplified GSM signal for transmission within a specified area. The transmitting antenna will then broadcast the amplified GSM signal wirelessly. The transmission part of the project was not achieved due to the effect of signal jamming in the area of transmission. This means that the incoming weak signal will be blocked by the strong signal being transmitted on the same frequency. However, further research in this area will help find a way out.
Project Title: Medical Tele-Consultation Unit
Student: Kwasi Kwakye Adomako
Supervisor: Mr. Stephen K. Armoo
Abstract:
The medical Tele-Consultation Unit was designed to be used at the Community -Based Health Planning and Services (CHPS) compounds operated by Ghana Health Services. The unit includes peripherals to measure body temperature, and pulse and oxygen in blood. It transmits the data to a nearby Health Centre for medical support through GSM. The personnel at the medical centre get the biometric data as well as the name, age and sex of the patient. The personnel at the medical center send recommendation back via SMS using the application. SMS can be scheduled for future notification, i.e antennal attendances. The usage of the GSM network for transmission and receiving enhances the flexibility of usage since mobile penetration is at 100% according to NCA and also it enables providing service in remote areas.
The System was implemented by sending the name, sex and age of the patient via SMS to the application, before the hardware unit was used. The hardware unit for the Biometrics consists of body Temperature Sensor, Pulse and Oxygen in blood Sensor, an Arduino microcontroller and GSM antenna, GSM module with a SIM inserted. The body temperature sensor was used to take the temperature of the person and the pulse and oxygen in blood sensor was used to take the oxygen saturation in the blood. These data were transmitted by GSM to the application system where it was accessed on a remote computer. A recommendation was sent from the system to the phone number where the name, sex and age originated from. SMS was scheduled to be sent at a later time, and there was a transmission at the scheduled time.
The system was tested and it worked as designed. A future recommendation is to add a blood pressure sensor and ECG sensor, which will in turn aid proper diagnosis, since that will give the medical personnel broader array of information for diagnosis.
Project Title: Securing Biometric Fingerprint Data Using AES & Digital Watermarking Techniques
Student: Quartey Yehonathan Raphael
Supervisor: Dr. Godfrey Mills
Abstract:
Biometric fingerprint has recently become the primary means of identification of people. Securing the fingerprint data both in transmission and storage is critical since data is unique and therefore in the wrong hands can have considerable implication. The focus of this work therefore is to secure the biometric fingerprint date using a combination of the Advanced Encryption Standards (AES) and digital watermarking technique.
The AES algorithm was developed using a 128-bit key to encrypt a captured fingerprint data. The resultant cipher data was converted into binary form and subsequently encoded into a digital face image using the singular value decomposition (SVD) technique as the digital watermarking method. The implementation was done on the MATLAB platform. To demonstrate the efficiency of the system, a captured fingerprint data of size 96 x 80 pixels was encrypted and subsequently encoded into a face image data of size 256 x 240 for transmission and storage. The final watermarked data was tested against various forms of attacks using FFT, rotation, and cropping to ascertain the sensitivity to external attacks. The CPU time lapse for the encryption process was an average of 10 seconds and 16 seconds for decryption.
Employing a combination of AES encryption and digital watermarking techniques proves adequate for securing biometric fingerprint data in transmission and also in storage. The fingerprint of individuals can be encrypted and then hidden in their passport photographs. The proposed work can be applied in biometric registration, for the creation of national ID cards, student ID cards as well as passports.
Project Title: GPS Location Based Advertiser, GPSLBA
Student: Isaac Nit Okpoti Quarshie
Supervisor: Mr. Stephen Kanga Armoo
Abstract:
The use of GPS technology in locating and addressing places is very common in the Western world. This is because it (the GPS) provides specially coded satellite signals that can be processed in a GPS receiver, enabling the receiver to compute the position, velocity and time. Most electronic gadgets have intelligent functionality components integrated into them. This due to the incorporation of microcontrollers into them. The combination of the microcontroller and the GPS technology has led to the development of fascinating systems that can automatically navigate their way without human intervention. Unfortunately, the use of this technology is not utilized in Africa since mapping and location addressing is not developed. The GPS Location Based Advertiser seeks to solve the problem of location addressing by incorporating both the microcontroller and the GPS technology.
This project is to design and develop a location addressing system with which a tourist can use to locate the name of places. The system is designed to have a microcontroller which is programmed to be able to interpret the signals it receives from GPS receiver connected to it. The microcontroller by the press button sends the interpreted signal to the LCD screen to be displayed as the name of the location and also to the speaker to pronounce the name of the location. The incremental process iteration model was employed in the development of this system.
The result obtained after testing the system showed that, the system was able to address the name of a specific location but was noise in the pronunciation. In the future, the integration of a GSM module would allow the system to access the Google map which would add GUI features to the device which would go a long way to enhance the efficiency and reliability of the system.
Project Title: Library Reservation System
Student: Richard Kojo Ghartey
Supervisor: Mr. Appah Bremang
Abstract:
The ineffective access and usage of the Balme Library by the University of Ghana students has become a threat to the academic performance of students. The Balme Library being the main library of the University of Ghana for students and most researchers outside the university are confound with limited learning spaces and congestion, the worse is during examinations when students need a place to study. The lecture rooms that could serve as alternative for studies are usually locked.
This project is to design and develop an online booking system with which students can book special rooms in the library for group studies for specific period of time in order to promote fairness and ultimate utilization of the library. The entries for bookings will be stored in the MYSQL database after the form has been submitted. A front end of the form of a user friendly Graphical User Interface (GUI) was developed using PHP and HTML. The project is an integrated system capable of receiving booking entries from students, allocation of rooms for a specific period of time and details of students who used the place will be stored in the database for tracking and statistical reports purposes.
The results obtained after testing the system showed that all entries were successfully stored in the database hence making the system reliable and support of management decisions. In the future, the development of a mobile application for the system to be accessed via mobile phones and also the development of a reminder via Short Message Service (SMS0- would go a long way to enhance the efficiency and system reliability.
Project Title: Voice Recognition System Using Artificial Neural Network
Student: Aaron Nichie
Supervisor: Dr. Godfrey A. Mills
Abstract:
Voice recognition is the process of identifying a speaker based on certain speech features that are unique to the individual. Identifying people by the unique features in their voices has been a great challenge. Most recognition systems available today use hidden Markov models and other techniques which include Dynamic Time Warping algorithm, Predictive Linear Coding. The intent of this work is to employ a combination of ANN and statistical algorithms to develop a voice recognition system.
The proposed method was a multi-layer perception artificial neural network which was used to learn the unique patterns in the human speech waves. The multi-layer perception was made of an input layer with twenty neurons, hidden layer with thirty neurons and an output layer with number of neurons determined by the number of speakers modelled in the codebook. The Mel Frequency Cepstral Coefficients algorithm was used to model the individual speakers. To decrease the rate of false acceptance and false rejection the ANN was combined with other statistical algorithms included Gaussian Mixture Model, Euclidean distance and Correlation.
To validate the performance, the system was tested using two different sets of voice data; a short phase, “how are you” and a long phrase; ‘good morning everyone in level 400 class” from two different individuals. Results for the short phrase data recognition gave an average recognition rate between 58.31% - 70.24% and a long phrase gave recognition rate between 50.33% - 60.65%. These values are consistent with reported values in literature using different techniques. The drop in the recognition rate between the short and long phrase was due to the fact that the long phrases increased the complexities of the voice pattern.
Project Title: GSM Based Car Security Control System
Student: Attuquayefio, Rodney Nii Kortei
Supervisor: Mr. Appiah Bremang
Abstract:
The frequent number of car theft cases reported over the past years has been alarming in the country which has necessitated installation of security systems in the vehicles. However, the reliability of these systems has become problematic to the security agencies and vehicle owners since it is often broken into rendering the security system ineffective.
To solve the problem, a system is developed and integrated in to the existing car ignition or starter system to control “on’ or “of” state through the use of relays. Users or vehicle owners can now immobilize their vehicles as an anti-theft measure or stop their vehicles (whiles in motion) remotely whenever the need arises by cutting off the engine provided they connected to a GSM network.
This project stands to benefit both the security services and individual vehicle owners. The security services can use this to fight crimes related to car theft whereby vehicles in motion can be stopped any time a suspect attempts to escape from law enforcement with vehicle in order to jump arrest or boot with the vehicle. In future, the work could be extended by incorporating Global Positioning System (GPS) to determine the precise location of a stolen vehicle for it to be traced after it has been locked and/or abandoned, thereby enabling the security services to retrieve these stolen vehicles. This could greatly increase the efficiency and functionality of the system.

Project Title: Intelligent GSM Signal Neutraliser, IGSN
Student: Samuel Asamoah Tekyi
Supervisor: Mr. Stephen Kanga Armoo
Abstract:
In modern- day Ghanaian society, the use of cellular phones have become popular to the extent that majority of the population prefer to use the device to the old fashion land line telephone system. The common nature of mobile phones has turned to frustrating or annoying a lot of people in the country, be it the sound of its ringing or the shouts of a user talking on the phone. Both the telecommunication consortium and the cellular device manufacturers are of these complains and are putting in less effort t address the problem. This project builds a device that will corrupt the downlink signal of all GSM operating cellular devices within an operating radius.
In order to build a system capable of preventing unwanted mobile phone intrusion, the maximum transmission power (TP) of the cellular industries must be known, the operating frequencies used in modulating must also be known so that a counter system can be designed to hold a jamming power (JP) as close as possible to the TP which will end up reducing the quality of transmission to about 12Db (SNR), where beyond this point, a dead zone will be realized for all cellular operating devices in that defined jamming radius. It was realized that the generation of a true noise within the tone frequency range will be effective enough to corrupt the cellular signal so effort was made to build a system that was capable of preventing cell phones from operating within a restriction zone by carrying a noisy signal on the GSM carrier hands used in the country.
A National Investment Multisim circuit simulator was used to design the system’s power and turner wave circuit. The turner output was designed to serve as an input to a voltage control oscillator (VCO) which will generate radio frequencies base on the instantaneous voltage level of the turner signal at its input. From the VCO, the power of the modulated signal is amplifier and propagated by an Omni - directional antenna. The finished product was tested on two smart phones which showed undesirable results. In the conclusion parts of the paper, recommendations have been made based on challenges faces during the design and building process.

Student: Kwaku Okyere Kankam
Supervisor: Dr. Godfred Mills
Abstract:
The ability to use mobile phones has become an attraction in recent times. Due to this fact, it is now possible to remotely control and regulate electrical devices using the mobile phone. This project seeks to design and implement a system for remote control and manipulation of electrical devices using the SMS technology.
The system design was structured into two major models. The transmitter and the receiver model. The transmitter model involved a client device which is a mobile phone with SMS capabilities and on a GSM mobile network. The receiver model is the control system which consists of a Microcontroller Unit (MCU) connected to a relay device on one side and a GSM on the other side. The GSM mobile phone received SMS instruction from a remote location. The Microcontroller unit (MCU) reads and decodes the SMS received. Upon decoding the instructions, the microcontroller unit controls the electrical device on or off with the help of the relay circuit.
To validate the performance of the system a prototype was successfully developed and tested by sending an SMS to the system. A green light on the system indicated that the device was on and a red light on the system indicate that the device was off.
Remove control and, manipulation of electrical devices has many uses of industry-wide. One application of this system involves the reading and manipulation of data in devices deployed in remote areas. In the petroleum industry, devices can be monitored and regulated using this system.
Project Title: GSM based Irrigation Monitoring and Control System
Student: Rockson Agyeman
Supervisor: Mr. Stephen Kanga Armoo
Abstract:
The development of the agricultural sector in Ghana for sometime now has been largely reliant on the use of irrigation systems. However, the manual operation of these systems has not facilitated their maximum efficiency due to human limitations.
The purpose of this project therefore, was to design and implement an automated system which monitors and controls the water flow of irrigation through communication with an authorized operator via test message. The control component of the system was automatic and timer based using an Atmega32 microcontroller and a real time clock from the SM5100B cellular module. The monitoring aspect of the system send periodic notification via SMS to the authorized person(s) in charge of the system o the performance duty. The GSM based Irrigation Monitoring and Control system was broken down into eight subsystems, each subsystem developed at a time and in a repeated cycle while integrating with each other.
The system which took 32 weeks to implement, proved very efficient. Aside serving as a means of assessing the efficiency of farm irrigation equipments due to its efficient system operation data logging capability, the GSM based Irrigation Monitoring and Control System saves time, labour and reduces cost of operating irrigation system by saving power and conserving water.
Project Title: Android Application for Election Monitoring
Student: Lartey Louis- Mark Nii Larte
Supervisor: Mr. Percy Okae
Abstract:
This project was implemented to provide a means of monitoring election results in Ghana in real-time using the Android mobile platform.
In Ghana, having instant access to election results is difficult hence there is a need to provide a means of delivering accurate, real-time and valid election results to the general public during the election period so as to avoid inconsistencies in the various results announced by the media.
This project tackled the problem by using a mobile application developed using the Android mobile platform.
It was observed upon testing that there was the possibility of letting the end-user access information from a database in real-time (but usually dependent on the speed of the available network) and also provide the mobile phone a local database (using SQLite).
The application made it possible for the mobile device to communicate with the remote database and also query the data base. There was an authentication process implemented to ensure that only authorised users were able to make changes to the database. Users were able to view results by categories such as National view, Regional view, and constituency view. For each category, the application provides both presidential and parliamentary results.
This project could be expanded to cover other parts of Africa. Extra features like graphs and possibly news on elections from various media houses could be inculcated into the application to enhance its functionality.
This project makes it possible for the general public to access information on elections. It also provide an alternate means for the Electoral Commission to also communicate results to Ghanaians apart from radio and television. The mobile industry is very vibrant in Ghana hence the application can easily be accessed by all.
Project Title: A Multi-Sensor Fire Detection and Notification System Using Fuzzy Logic
Student: Selase Newton Krakani
Supervisor: Dr. Robert Sowah
Abstract:
Notwithstanding massive fire safety campaigns being carried out, incidents of fire outbreak around the country continue to increase annually. The alarming rate of these fire outbreaks requires a solution system that detects fire in its early stages and contributes to the fire fighting effort.
The invention of the smoke detector in the 1930s revolutionized fire detection. This remained the primary method of detecting fires for decades. In order to improve performance of these systems, current research efforts have been directed towards the development of multi-sensor fire detection algorithms. Multi-sensor fire detection system employs more than one sensor. This increases the sensitivity of the fire detection device and reduces nuisance alarms.
The purpose of this project was to design and implement a multi-sensor fire detection and notification system using fuzzy logic. The notification subsystem was implemented to remotely notify the GNFRS and the owner(caretaker)of a building of a fire outbreak in real-time. The Arduino Uno microcontroller processes data from an MQ2 smoke sensor, a TMP 102 temperature sensor and a DFRobot fame sensor using a fuzzy logic algorithm to determine the fire status. A SIM900 GSM module was used to send fire alerts to the owner of the building and the web based fire notification subsystem in real time. A map assisted navigation system was also implemented to aid fire fighters locate fire scenes quickly.
Aside its ability to better discriminate between fire and non fire situations compared with standard fire detectors, the system has the added benefit of aiding fire fighters. By providing location based notification of fires in real-time and assisting the fire crew locate the fire scene, response time is greatly reduced.
