Computer Simulation of Uncoordinated Dynamic Channel Access Method in Cognitive Radio Network for Radio Terminal Device

Grebeshkov, A., Zuev, A.

Abstract. An implementation of the cognitive radio networks raises an issue of the medium access control (MAC) protocol researching, in particular MAC protocol impacts on the access delay to radio channels. In this paper uncoordinated access method is studied where the event of spectrum and channel accessing is random and determined by probabilistic value from 0.1 to 0.99 named as channel availability. The subject of research was impact of channel availability on the access delay with simulation on the base ns2 program simulator with CRNC patch.
