(English 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 proposed
scheme 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.
