Abstract

An ad hoc network has notable features such as frequent mobility, bandwidth limitation, and power constraints. Especially, due to the low bandwidth, there is a strong possibility to cause congestion. If there is congestion, however, power depletion and queuing delay will be serious problems in mobile nodes. In this paper, we propose a Weighted Load Aware Routing (WLAR) routing protocol, which shows excellent performance in an ad hoc network. WLAR Protocol, an extension of AODV, is to distribute the traffics among ad hoc nodes through load balancing mechanism. A new term of total traffic load is defined as a route selection metric, which is the product of average queue size and number of sharing nodes. Using NS2 simulator and real implementation, we show the performance, comparing to AODV.
