Title: A Survey of the Primary User Emulation Attack in the Cognitive Radio Networks Authors: Olaleru, Grace; Ohize, H; Dauda, U. S.; Mohammed, Abubakar Saddiq Abstract: Cognitive Radio Technology (CRT) helps alleviate the spectrum scarcity and spectrum underutilization problems experienced by wireless networks and wireless devices by enabling the intelligent and opportunistic use of the licensed frequency band by unlicensed users. However, due to its wireless nature, it is subject to some security threats that affect the practical implementation of the CRT. In this paper, we have discussed some of the security threats affecting the protocol stack and the five layers of the Cognitive Radio Network (CRN), with a focus on the Primary User Emulation Attack (PUEA). The PUEA is one of the most common attacks on the CRN’s physical layer. In this attack, a selfish or malicious user mimics the primary user's (PU) signal features to fool the legitimate secondary users (SUs), causing the legitimate SUs to leave the available channel while the real PU is absent. Although many review papers enhanced our knowledge of the PUEA, in this paper we meld new research findings with the old ones to keep up the pace in the research community. Also, we discussed some detection and countermeasures for the PUEA in the CRN. Finally, a summary of the findings on how best to mitigate the effect of PUE attacks in the CR is presented.

Title: Development of a Vehicle Speed Monitoring and Reporting System Authors: Danaladi, Clement; Mohammed, Abubakar Saddiq; Abdulkarim, Hauwa Talatu; Usman, Abraham; Yakub, Mohammed; Paul Abu, Agwu Sunday Abstract: A speed monitoring and reporting system is one of the major systems required to curb the issue of sudden accidents due to reckless driving and over-speeding. Traffic surveillance has become increasingly crucial in today's world, where the number of vehicles on the road has risen significantly. To preserve the safety of motorists, traffic law enforcement assigns speed limits at different locations throughout the country. However, irresponsible motorists still exceed the speed limit, since they know it is unlikely that they will get caught. In this project, a system is developed that is capable of detecting moving vehicles in a video and displays the vehicle's speed as it goes. Should a vehicle exceed the allowed speed limit, it will snap a photo of the vehicle and extract the license plate number region so it can be sent to the traffic law enforcement agency to take necessary action. The system uses MATLAB as a simulation platform since it provides a comprehensive toolbox such as image processing toolbox and techniques; background separation, feature extraction, edge detection, and morphology operations used with the advantage of web services to send mail to the required authority.
