Weighted load balanced routing protocol for MANET

摘要

AODV is a prominent routing protocol for MANET that uses hop count as a path selection metric. However, AODV has no means to convey traffic load on current route. In this paper we propose a weight-based load balanced routing (WLBR) protocol for MANETs. The routing strategy projected in this paper focuses on distributing the traffic on the routes consisting of nodes with comparatively longer life and have less traffic to pass through. In this paper we also introduce a new metric, Aggregate Interface Queue Length (AIQL), to deal with traffic issue. The weight of a route is decided by three factors: the aggregate interface queue length, the route energy and the hop count. The route with highest weight value is selected for further data transmission. Performance evaluation through simulation shows that the proposed protocol (WLBR) performs better than AODV protocol.
