On the Evaluation of Handover Exchange Schemes Between Two Cognitive Radio Base Stations with and without Buffers

Ebenezer Esenogho, Elie Ngomseu Mambou, Hendrik Ferreira


This article investigates and evaluates a handover
exchange scheme between two secondary users (SUs) moving in
different directions across the handover region of neighboring cell
in a cognitive radio network. More specifically, this investigation
compares the performance of SUs in a cellular cognitive radio
network with and without channel exchange scheme. The investigation
shows reduced handover failure, blocking, forced and
access probabilities respectively, for handover exchange scheme
with buffer as compared to exchange scheme without buffer.
It also shows transaction within two cognitive nodes within a
network region. The system setup is evaluated through system
