Research on Trust Computation Models in Wireless Sensor Networks

Abstract:

Wireless Sensor Network security is not only threatened in the time of passing information between nodes, but also in processes of data generation. Cryptography is therefore unable to prevent attacks from nodes inside the network after those nodes have been captured. The trust model can play an important role in this aspect. It can effectively identify malicious nodes, self-ish nodes, and low competitiveness nodes in the network to improve its performance. This paper focuses on the technical characteristics of trust management and design. It classifies existing trust computation models into several types according to their computing theories at first. Then it discusses several classic trust management frameworks and analyzes their advantages and weaknesses. At last, the paper concludes general problems of current models and points out future research directions.
