Performance analysis of cross-layer efficient selfishness prevention routing protocol for the dynamic CR networks

Abstract

As wireless communication is very dependent on the use of spectrum, increased demand for and practical application of new wireless services generally leads to spectrum shortages. A remarkable feature of protocols in the cognitive radio is to, to detect the selfish behaviour of node and discard the abnormal packets. However, minimize transmission latency and enhance energy efficiency are two main issues in multi-hop Cognitive Radio Networks (CRN) where it is difficult to gain knowledge of topology and spectrum statistics. The misconduct of selfish nodes such as not participating in the routing process, delaying RREQ packet intentionally, removing the data packet, not responding or sending hello messages. This misconduct of the selfish nodes will affect efficiency, trustworthiness, and fairness. This paper proposes the cognitive radio dynamic nature, associate with that of selfish nodes, the cross-layer efficient Selfish Prevention Routing Protocol (ESPRP). All the above characteristics are simulated with help of NS-2.35 simulator, and our proposed protocol attains good enactment in terms of lower delays, higher throughput and better packet delivery ratios for collaborative node traffic related to traditional routing protocols in the cognitive radio.
