Abstract

Source authentication and message integrity become a fundamental requirement for ad-hoc network. In this paper we are using Clustering is an effective technique to reduce overhead and ensure scalability. The proposed work is a new Tiered Authentication scheme for Multicast traffic (TAM), using a dynamic clustering algorithm. This algorithm modifies Weighted Clustering Algorithm (WCA) with mobility prediction. Weighted Clustering Algorithm itself is improved with the use of mobility prediction in the Cluster Maintenance phase. Since the nodes are mobile in MANET maintenance is essential. Effective utilization of power, Minimum wastage of Bandwidth, More Stable Clusters by using WCA helps in improving the QOS in MANETs.
