Location Aware Reduced Diffusion Hybrid Routing Algorithm (LARDHR)

Mobile ad-hoc network (MANET) is a multihop wireless network formed by a collection of mobile nodes wherein the nodes move arbitrarily thus making the topology dynamic. MANETs have low bandwidth wireless links hence the routing protocols with less consumption of bandwidth are of great importance. This paper presents a new location aware hybrid routing algorithm with reduced diffusion of routing related messages called location aware reduced diffusion hybrid routing algorithm (LARDHR). This algorithm utilizes different mechanisms to reduce the diffusion of route search messages in the whole network and also encourage the route stability to save the limited energy of the anemic mobile nodes. With the help of physical locations of the nodes route search messages are routed only through limited nodes therefore the algorithm utilizes the bandwidth optimally and also increases the efficiency of the route search method.
