This paper introduces a trust-based multipath routing protocol for exploiting different paths between source as well as destination to mitigate energy constraints. The key idea is to determine optimal path from the entire paths available among source and target node. To improve the security in routing protocol, the factors, like trust factors, and distance are considered as major components. Based on these parameters, the multipath routing is carried out based on HH-Jaya Algorithm. The HH-Jaya is designed newly by integrating Harris Hawks Optimization (HHO) and Jaya Algorithm. After that, the reputation and trust-based context aware routing (RCAR) protocol is utilized to select the optimal path with more trust factor. Here, the trust is modelled by considering trust factors, like direct, indirect, history, forwarding rate, and availability factors, in addition to the utility function. The proposed HH-Jaya outperformed other methods with minimal delay of 0.007 sec, maximal throughput of 0.913 for 10 user and maximal packet deliver rate (PDR) of 0.991 for 20 users respectively.
