Mobility Enabled Trustworthy Architecture for Wireless Sensor Networks

G. Mangalesh, S. T. Uma

Abstract: A Wireless sensor networks (WSNs) consist of small, lightweight wireless sensor nodes which are randomly deployed in large numbers to cooperatively monitor the physical or environmental conditions, such as pressure, humidity, temperature or pollutants. Ensuring security for the WSNs is a critical issue nowadays. Traditional security schemes cannot always be applied to WSN. Therefore, modeling concepts like trust and reputation is applied to gain a certain level of security and confidence among inter-operating nodes. Trust is calculated for a sensor node based on past interaction experiences given by neighbor nodes for assessing the reliability. It was also to measure the security property of a node (e.g. whether a node is malicious or not). Trustworthy Architecture for the WSNs provides the trusted communication among the sensor nodes, based on trust and reputation models. In this paper, mobile trust node was introduced to calculate the trust value for each and every sensor node in WSN and also analyzed the performance metrics of mobility enabled trustworthy architecture for WSN. This concept increase the lifetime of WSN by reducing communication overhead Performance analyses were carried out by using the Network Simulator (NS2).
