A Cognitive Improved Hierarchical AODV Routing Protocol for Cognitive Wireless Mesh Network

Pei Tingrui, Zhao Zhi, Zeng Wenli and Zhang Zhaoxia
Routing is the main research issue in the development of Wireless Mesh Networks (WMNs). Many of the routing approaches have been borrowed from Mobile Ad hoc Networks (MANETs) to achieve routing solutions in WMNs but are not ideal or optimal and do not utilize the characteristics of WMNs to fulfill their benefits. Moreover, these approaches don’t take into account the cognitive radio environment. In this study, we propose an improved hierarchical AODV routing protocol based on cognitive radio (CIH-AODV) for cognitive wireless mesh network, which exhibits better scalability and performance in the network and incurs less routing overhead for finding alternate routes when a route is lost. Furthermore, we present a novel technique for CIH-AODV termed fresh route detection which is designed to support cognitive radio. We make comparison between AODV and CIH-AODV in our simulation using NS-2. Simulation results show that the metrics of CIH-AODV are better than or comparable to AODV in hybrid WMNs and the protocol is suitable for the cognitive radio environment.
