Abstract

Nodes of Wireless Adhoc networks have restricted bandwidth resource, and comprise high mobility. It has a high link breakage rate and so partitioning rate of the network is considerably high. Routing in MANET's is very complex because of node mobility and limited communication resource. Topology changes and breakage of exiting paths occurs repeatedly due to the mobility of nodes. A routing protocol should quickly adapt to the topology changes and efficiently search for new paths with minimal power consumption. We propose an adaptive weighted cluster based routing for mobile ad-hoc networks which amends swiftly to the topological changes and establishes the routing efficiently. In our proposed approach, the cluster head selection is performed by assigning a weight value based on the factors Energy Level, Connectivity and Stability. We show by simulations, that the performance of our proposed protocol surpasses the existing adhoc routing protocols in all aspects.
