Role Based and Energy Efficient Trust System for Clustered Wsn
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 2
Abstract
Security and trust are two interdependent concepts and are often used interchangeably when defining a secure wireless sensor network (WSN) system .However, security is different from trust in that, it assumes no node is trustworthy and requires ongoing authentication using sophisticated protocols leading to high communication and computation overheads. This makes the traditional cryptographic security tools hard, if not impossible, to be used in wireless sensor networks that are severely resource constrained. Trust on the other hand is the exact opposite of security in that any node can interact with any other and requires no authentication and mapping of hidden keys to carry on with their business and hence carries zero overhead. Trust management scheme calculates the trustworthiness of the node. Several trust systems have been proposed for the WSN.But they suffer from various limitation such as high cost and overhead. So light weight trust system is necessary because of the node’s resource constrained nature. This proposed system provides light weight trust decision making and it improves the dependability of the system by cancelling the feedback between clustered members. It uses self adaptive weighting scheme for trust aggregation. Thus, it needs less memory and communication overhead
