Abstract

A mobile ad-hoc network (MANET) is an autonomous, infrastructure-less system that consists of mobile nodes. In MANET,on-demand routing protocols are usually used because network topology changes frequently. AODV, which is a representative on-demand routing protocol, operates using the routing table of each node that includes next-hop of a route for forwarding packets. It maintains the established route if there is not an expiration of route or any link break. In the paper, we propose a partially adaptive route maintenance scheme (AODV-PA) based on AODV, which provides dynamic route modification of initial route for selecting the effective route using not only next-hop but also next-hop of next-hop (i.e. 2-hop next node) acquired through route discovery process. In addition,the proposedscheme additionally manages the routing table for preventing exceptional link breaks by route modification using HELLO messages. We use NS-2 for the computer simulation and validate that the proposed scheme is better than general AODV in terms of packet delivery ratio, latency, routing overhead.
