Link quality aware local repair in AODV-based Ad-hoc networks

Abstract

Route recovery process of Ad-hoc On-demand Distance Vector (AODV) protocol has been extensively studied. However, the recovery process still requires long delays and overheads. In this paper, we proposed a link quality aware local recovery protocol for AODV based Ad hoc networks. In the proposed method, when a link is broken, a node detecting a link-break asks to neighbor nodes who can be a substitute for a node causing the link- break. If there is such a node, then the recovery is quickly and locally completed. The proposed method does not increase overhead to find the substitute link comparing to the conventional AODV protocol. The results show that proposed protocol performs better than source repair and local repair in term of throughput. The simulation is done through Network Simulator (NS-2).
