Mobile ad- hoc network is one of the most effective self-configuring and infrastructure less based communication networks. During the communication process, trust between the networks is placed an important issue due to the intermediate attacks. Several types of research introduce the trust-based communication protocol for overcoming privacy issues but still, the efficiency of the trust is one of the major problems. So, this paper introduces the optimised trust and energy efficient multipath routing protocol based on the maintained energy of the node to overcome the issues. The intermediate attack in the network has been eliminated with the help of the trust and dynamic with energy efficient multipath routing protocol. The established trust has been used for a multipath routing protocol. Then, the efficiency of the system is analysed using the packet delivery ratio and security. The method ensures the trust in the network by applying the computation, aggregation, and propagation and prediction process.
