ASCM: An autonomous Subtree-Based clustering scheme for MANET

A Mobile Ad Hoc Network (MANET) is a wireless network which provides communication among wireless mobile hosts without the need of any pre-established infrastructure or centralized control. In such environments, organizing mobile nodes into manageable groups called clusters can reduce the routing overhead and provide better coordination among the nodes. When the nodes mobility is high, re-clustering is one of the major issues to be considered in MANET. The proposed system ASCM, is an autonomous clustering scheme based on Subtree-Based tree structured approach, which carry out the re-clustering using highest connectivity and low mobility factors in order to maintain an efficient backbone structure. It found that ASCM improves the performance of cluster formation, using NS2 simulator.
