Improved hierarchical AODV routing protocol for hybrid wireless Mesh network

Zhao Zhi

Open publisher page 1 citations

Abstract

Routing is the main research issue in the development of Wireless Mesh Network(WMNs).Many of the routing approaches have been borrowed from MANETs to achieve routing solutions in WMNS but are not ideal or optimal and do not utilize the characteristics of WMNs to their benefits.In this paper,an improved Hierarchical AODV routing protocol (IH-AODV) is proposed,which exhibits better scalability and performance in the network and incurs less routing overhead for finding alternate routes when a route is lost.Furthermore,a novel technique for IH-AODV term fresh route detection is presented.This paper provides comparisons of both AODV and IH-AODV in the simulation using NS-2.Simulation results show that IH-AODV scales well for large network and other metrics are also better than or comparable to AODV in hybrid WMNs.
