An Entropy-based Trust Modeling and Evaluation for Wireless Sensor Networks

Wireless sensor networks are hard to be stable and vulnerable to various attacks, so it´s a need to find the mechanisms to evaluate trustworthiness with trusted computing theories. In this paper, a novel entropy-based trust modeling and evaluation methods for WSNs are carried out to give the stability and security descriptions. With the experiments, it is proved that they can be used to detect the malicious nodes, to estimate the effect and the performance of WSN.
