SWCA Secure Weighted Clusterhead Election in Mobile Ad Hoc Network

Abstract

Mobile ad hoc networks (Manets) consist of a large number of mobile nodes communicating in a network using radio signals. Clustering is one of the techniques used to manage data exchange amongst interacting nodes. Each group of nodes called cluster and has one or more elected Cluster head, where all cluster heads are interconnected for forming a communication backbone to transmit data. Moreover, cluster heads should be capable of sustaining communication with limited energy sources for longer period of time. Misbehaving nodes and cluster heads can drain and reduce the total life span of the network. In this context, selecting the appropriate cluster heads with trusted information becomes critical for the overall performance. In this paper, we analyze the existing trust based clustering solutions, and highlight their advantages and drawbacks. Besides, we propose an efficient trust based cluster head selection.
