Abstract:

A dynamic trust model in mobile Ad hoc network (MANET) based on multiple factors decision (MDF-Trust) was proposed. Through quantifying the decision factors of state and behavior of the node, the routing node trust by multiple factors decision theory was evaluated. The deceptive behavior of malicious node was restrained by the trust model when introducing recommendation credibility and recommendation node searching algorithm. Simulation shows that the proposed trust model can reflect the node's trust changes accurately with better dynamic response ability with higher number of packet delivery and lower delay in the circumstance of existing deception nodes.

Key words: mobile Ad hoc network, multiple factors decision, dynamic trust model, routing node trust
