A light weight efficient cluster based routing model for mobile ad hoc networks (LWECM)

Abstract

In recent few decades mobile ad hoc network have gained attention among researchers due to its extemporized nature. Routing of packets in these networks is very challenging task due to the mobility of nodes and dependency on small battery to remains active in the network. Flat routing schemes impose the great control overhead over network and perform poorly when number of terminals is increases. Cluster based routing schemes for MANETs has evolved an important alternative as it allows the scalability of network and better utilization of resources. In many clustering schemes a cluster contains a special node called cluster-head. Cluster-head act as a coordinator in its cluster. Since the cluster-head has to perform additional tasks in compare to other nodes in the network therefore it becomes over loaded and drains its battery more rapidly than other nodes in network. In this work “A Light Weight Efficient Cluster based routing Model for Mobile Ad hoc Networks” (LWEC) is proposed in which the life of cluster-head is prolonged by reducing the unnecessary load on cluster-head.
