Performance Evaluation of AODV Routing Protocol in Cognitive Radio Ad-Hoc Network

Free registration required

Executive Summary

A cognitive radio is designed for the utilisation of unused frequency. The transmission opportunity of a cognitive node is not guaranteed due to the presence of Primary Users (PUs). To better characterize the unique features of cognitive radio networks, the authors propose new routing metrics, including Routing for CRNs using IEEE 802.11 which are the official standards for wireless communication. Routing protocols, for network without infrastructures, have to be developed. These protocols determine how messages can be forwarded, from a source node to a destination node which is out of the range of the former, using other mobile nodes of the network.
