Abstract
Since multiple factors can affect the node trust,this paper proposed the node routing vector threshold;based on RFSN(Reputation-based Framework for high integrity Sensor Networks) model,multi-factor trust model for wireless sensor networks was established by using routing vector threshold.Communication trust,energy trust and routing vector trust were all considered during the computation of node trust in this model.It could objectively show the degree of trust of a node and respond to a variety of security threats which wireless sensor networks encountered.The simulation results show that the model can more accurately identify the node trust,detect the malicious node early and prolong the network lifetime.
