Neighbor-Aware Clusterhead for SNET

Abstract

A wireless mobile sensor network is a collection of wireless mobile hosts forming nodes that are arbitrarily and randomly changing their locations and communicating without the aid of any centralized administration or standard support services. Nodes are classified as sensor nodes and router. Some nodes act both as sensors and routers. In this paper, we propose a novel cluster-based infrastructure creation protocol, namely: the neighbor-aware clusterhead (NAC). NAC establishes a dynamic wireless mobile infrastructure. We study the characteristics and performance of the NAC protocol by means of simulation. In NAC protocol nodes are synchronized with their clusterheads and are allowed to go sleep mode in order to conserve their energy without degrading the performance of the network. The network is divided into clusters managed by a clusterhead. The simulation results show that NAC protocol has a good potential to be a good candidate protocol for SNET.
