A Low Latency AODV Routing Protocol

Abstract

AODV is reactive routing protocol, used in MANET that establishes route between source and destination, whenever the source has data to send to the destination and there is not any route between them. Since nodes are moving route breaks because nodes are out of coverage of the neighboring nodes. After route break RERR messages are circulated to all the nodes, due to RERR messages traffic increases in the network. And again route discovery mechanism is initiated, in this situation there is a lot of delay. In this paper, authors proposed a method which is based on receive signal strength of the packets coming from neighboring nodes. This method avoid route break in advance. Simulation shows, this new protocol outperforms the original AODV protocol in terms of delay and throughput. Simulation is done on Network Simulator 2.
