Improvement of QoS Parameters using FAN Shaped Clustering Method

Abstract

Clustering in MANET provides greater efficiency in terms of energy and mobility of the node. It has better stability and scalability of the nodes in the network, as energy and mobility of node is the key parameter for the nodes in the network. Cluster Head (CH) selection and Cluster maintenance are the two perspectives for clustering in MANET. CH is the vital node in the network to collect the data from the member nodes. CH requires more energy when compared to other nodes in the cluster. It calculates the distance of the nodes and energy of the node in the cluster by the ration of energy and distance based on sector design. If energy of the cluster head is less than threshold value, the reclustering occurs and again a CH is elected. There are different geometries of the clustering, and Fan shaped clustering approach is proposed in this paper. This clustering scheme result is expected in terms of Quality of Service (QOS) parameters. QOS parameters have been evaluated with fan shaped clustering and without fan shaped clustering. QOS parameters such as throughput, packet delivery ratio, path loss etc. are validated on the NS2 Simulation Platform. It extends the network life in terms of energy throughput, delay and Packet Delivery Ratio.
