Analysis of Delay Performance in Multicast CPC Scheme

Guoping Chen; Songtao Liu; Pengfei Wu

Cognitive pilot channel (CPC) can provide the necessary wireless environment information for the terminals and avoid long time- and energy- consumption for spectrum scanning. In previous researches, two different CPC information delivery modes have been proposed, i.e., broadcast CPC and on-demand CPC. However, both mechanisms exist certain advantages and disadvantages. So a novel CPC multicast mechanisms have been proposed. Although, this mechanism improving the system’s access delay performance, there is still room of optimization. Because there is a limitations on research of mesh divided. This paper give a novel algorithm which make access delay of multicast CPC more optimized. Simulation results show that the proposed algorithm significantly improves the performance of multicast CPC scheme.
