Abstract

In this paper, we consider a collaborative routing strategy in cognitive radio network. We define a system model and a pricing scheme as a means to stimulate cooperation in users. Assuming that cognitive radio base station sets prices for the network profit maximization according to the interferences caused by secondary users to primary users, we propose an iterative price adaptation algorithm to allocate spectrum properly and develop a relay routing algorithm which combines spectrum allocation with route selection. Simulation results show that the price-based spectrum-allocation relay (PbSAR) routing can mitigate the interference and increase the network throughput greatly.
