IPSAG Cognitive Radio Routing Protocol: Models and Performance

Executive Summary

The paper is about performance evaluation of the IP Spectrum Aware Geographic routing protocol (IPSAG). IPSAG is an opportunistic cognitive routing protocol, which determines a source-destination route in a hop-by-hop manner, based on global and local information. Simulation results are reported for a particular case of IPSAG, where the Cognitive Radio (CR) nodes are uniformly distributed inside the Cognitive Radio Network (CRN) and a two-dimensional random walk model is used to model the mobility of CR nodes. The results show that the IPSAG protocol is performing well in the case of a highly mobile CRN and that the source-destination path is successfully found in the majority of cases, especially when the network is highly populated.
