A Coverage-Preserving Node Scheduling Scheme Based on Trust Selection Model in Wireless Sensor Networks

Abstract

Wireless sensor networks consist of a large number of low power shot-lived, unreliable sensors, one of the main design challenges is to obtain long system lifetime, as well as maintain sufficient sensing coverage and reliability. In this paper, a trust selection model is proposed by virtue of behavior experience in human society. In this trust model, multiple evaluation preference adjustment strategy and trust update mechanism is used to improve the reliability and accuracy. And in this paper, by establishing the trust relation and estimating the trust degree of the wireless sensor nodes, a node-scheduling scheme for wireless sensor network is achieved based on the trust selection model
