Abstract:

Due to the openness and dynamic natures of the mobile ad hoc network topology, traditional routing protocols are vulnerable to various attacks from malicious nodes. This paper proposes a trust calculation model combining direct trust with recommendation trust. Direct trust is calculated by fluctuation-based system cloud grey prediction model, recommendation trust is calculated by different types of recommendation nodes, and the weights of direct trust and recommendation trust are determined dynamically to get the total trust value. Based on this trust model, this paper designs a fluctuation-based trust multicast routing protocol BTCMRP. The agreement can identify and eliminate malicious nodes in the network through trust calculation, and effectively deal with routing attacks. In routing maintenance, the forwarding group node reuse mechanism is proposed, which solve the problem of excessive multicast routing overhead in multi-source grid structure. The simulation results show that compared with the proposed trust-based multicast routing, BTCMRP improves the delivery rate and reduces the routing overhead and average delay.
