Resource management based secure trust model for WSN

Abstract

Trust evaluation models are vital security enhancement tool for Wireless Sensor Networks (WSNs) to improve dependability (cooperation) among sensor nodes. This paper presents an Accurate and Efficient Distributed Trust Model for WSNs, which focus on fundamental requirements (resource efficiency) and security improvement. The proposed mathematical model (TSTM) computes trustworthiness of communication as well as data (transmitted) more accurately and precisely than other states of the art trust models such as LDTS, ADTC, and LWTM, etc. The proposed scheme consists of unique features like authentication based data trust, scheduler based node trust, and attack resistant by giving the high penalty and minimum reward during node misbehavior. The proposed trust model would be capable of providing security against various internal attacks due to consistency in trust values.
