T. Kumar, R. Muthukumar, N. Shanthi . Review of Mobility Aware Clustering Scheme in Mobile Adhoc Network. International Conference on Research Trends in Computer Technologies 2013. ICRTCT, 1 (February 2013), 19-24.
In Mobile Adhoc Network (MANET), hierarchical network architecture is created for improving the performance parameters like scalability and stability. Clustering is one of the typical hierarchical network structures which groups the geographically adjacent nodes into same cluster. By creating such kind of basic clustering structure, scalability can be improved, but high mobile nodes in the network may change the topology dynamically, which may affect the clustered network structure and decreases the stability of the network. For creating more stable and scalable network, clustering must accounts mobile node's mobility behavior for clusterhead selection, cluster formation and cluster maintenance. In mobility aware clustering scheme, the mobile node's mobility behaviors (distance, speed, acceleration, and relative velocity) are estimated first at regular intervals of time. By using this estimated mobility behavior geographically adjacent mobile nodes are grouped into a cluster, and node having the low mobility or low relative velocity is selected as a clusterhead. This mobility aware clustering structure improves the network stability by reducing the least clusterhead change, number of re-affiliation, and association loss. Most of the recent research papers in MANET are focused on mobility concerned clustering algorithm, and hence this paper focuses only on mobility aware clustering instead of various clustering scheme available. This paper comprises of comprehensive survey of mobility aware clustering algorithms for MANET.
