Abstract

Long-distance wireless communication is facilitated by IEEE 802.16e, the Worldwide Interoperability for Microwave Access technology. Rather than increasing bandwidth, this research focuses on dualization, or splitting of channels to optimise handover calls during mobility. Reducing wasteful scanning and improving the handover situation on the network handover efficiency improved in locating a target base station were achieved via the implementation of an enhanced cognitive radio technology provided here. It should be mentioned that the goal of this research project was to reduce unneeded delays, reduce the number of NBSs that need to be scanned, increase throughput, and reduce the rate at which handovers fail. The intensity of the signal received, data, failures handover, and data rate all were gathered during an empirical field measurement to ascertain the signal strength from Nigeria's mobile telecommunications company, MTN. Furthermore, MATLAB was used to create a model. Simulink demonstrated through its simulations that network operators must continue to enhance network performance in order to ensure quality services. The proposed enhanced cognitive radio model is used with various mathematical assumptions as presented on this dissertation research work and was validated using MATLAB version 16.0 program. The Enhanced Cognitive Radio Technology as seen from our analysis showed greater improvement in handover failure reduction than any other radio technology. However, enhanced cognitive radio were frequencies are optimally managed through frequency dualization scheme and idle frequency borrowing scheme, were efficiently managed in this research work. a simulation was carried out which show a great improvement when analyzed on the simulated graphs.
