Study on Techniques for Cluster Head Formation over Mobile Ad Hoc Networks

B.Sindhuja, Dr.J.Shanthini

Mobile Ad Hoc Networks (MANET) is a network composed of many nodes via wireless links which has dynamic topology in nature. Nodes of MANET are divided in to clusters for temporary communication from source to destination. Each node in a cluster is supervised by a leader node known as cluster head (CH). The works of cluster head is to maintain the affiliated node list and also to communicate with the other clusters. Maintaining of cluster head has some advantages like it allows fast communication, topology management, better routing. Cluster head improves the performance of network parameters like routing delay bandwidth consumption and throughput. For cluster head selection the parameters like mobility, connectivity, battery power etc. This paper presents the survey of different schemes for choosing the cluster head and comparison of weights that are given to different parameter factors and decisions are taken after calculating the weights of the nodes.
