RDCLRP-route discovery by cross layer routing protocol for manet using fuzzy logic

Abstract

MANET links have dependency on node mobility and node battery power causes degradation of network's performance and it could be alleviated by allowing cross layer interaction in the protocol stack. In this paper Route Discovery by Cross Layer Routing Protocol (RDCLRP) is proposed for route discovery and route maintenance and AODV is modified. Instead of periodic hello message of AODV, non periodic hello warning message is used for route maintenance and route discovery in RDCLRP. HELLO warning message is used to give warning when link is going to break before link breakage when it touches the threshold and it is broadcasted whenever it is required and not periodically. With the help of Hello warning message new route can also be discovered before link breakage. In this paper only HELLO warning message interval is optimized with the help of fuzzy logic. This reduces overhead and power consumption, in turn it reduces delay in search of new route. The result illustrates the improvement of optimized RDCLRP over the basic AODV. Network performance such as throughput, delay, jitter, overhead and battery power consumption can be improved significantly with this method. © 2011 Springer-Verlag.
