Weighted Dominating Set Based Energy Efficient Routing in Wireless Ad Hoc Network with Stable Nodes

G. Shenbagalakshmi, T. Revathi

Abstract

A mobile ad hoc network (MANET) is a self-configuring, infrastructure-less network with inherent flexibility.Mobility of nodes in these networks often results in changes in network topology due to the formation of new links and the extinction of the old ones, which may result in packet losses.In spite of such daunting challenges, MANETs promise to be an ever-present technology and have proven useful in a wide range of areas.Researchers are interested in assessing the reliability and stability of such dynamically changing networks.The proposed distributed algorithm reduces the frequent route failures by incorporating route stability into routing which helps to sustain network operations over an extended period of time. Here, a subset of network node named Weighted Connected Dominating Set (W – CDS) is selected based on the stability factor, which consists of link stability, node degree and mobility to achieve the maximum network lifetime. Then, the redundant nodes are removed by the pruning technique considering energy parameter. The simulation results show that the proposed protocol provides data forwarding support with fewer CDS nodes and thereby increases the lifetime of the network. It creates less interference and consumes less energy when compared to the other existing techniques.
