Abstract:
Mobile ad hoc networks (MANETs) refer to networks formed by mobile nodes without fixed infrastructure. In a highly populated MANET, involving each and every node for data communication will lead to wastage of resources. So clustering is preferred in MANET. Since Cluster head is the key for network performance, the selection of cluster head is an important task. In this paper a trust based weighted clustering algorithm (TBWCA) for finding reliable cluster head is proposed .The objective of the proposed algorithm is the prevention of malicious node from cluster head selection. We evaluated the performance of the proposed algorithm using Network simulator (NS2). The simulation results illustrate the superior performance of the proposed algorithm in terms of reliable cluster head selection and improved throughput.
