Secure routing based on trust model and reference node strategy in Ad Hoc network

Abstract

Ad Hoc network is a kind of wireless mobile network that does not depend on any fixed infrastructure. It has the characteristics of no center, self-organization, and high dynamic and limited energy. Therefore, Ad Hoc network has security risks. The Ad Hoc secure routing based on the trust model and the reference node strategy provides a secure environment for the establishment of communication routing. The AODV routing protocol is improved. The protocol selects a trusted communication node to establish routing according to the comprehensive evaluation result of the trust model, and finds out the data message discarding the attack node by the trust model. At the same time, the reference node strategy is proposed to defend the black hole attack node. Theoretical analysis and simulation results show that the proposed secure routing scheme can effectively detect and isolate malicious nodes, resist black hole attack and data packet attack attacks, and has high security characteristics.
