Energy Based Trustedsource Routing Protocol for Mobile Adhoc Networks

Secure transmission in Mobile Ad Hoc Networks has proven to still be a challenging task due to the openness in network topology and absence of a centralized administration. In order to enhance the security of network and protect the nodes from vulnerabilities, this paper proposes a novel energy based trusted routing scheme to select the most trustable path based on the route trust and also the energy level of nodes in the route. The path obtained by using this scheme not only includes the nodes with high trusted values but also excludes the nodes which have low residual energy. We have integrated the proposed model into the popular DSR routing protocol. Our novel on-demand trust-based source routing protocol for MANETs, called as Energy based Trusted DSR routing protocol (ET-DSR), provides a flexible and feasible method to choose the route that meets the security requirement of data packets transmission. Extensive experiments have been conducted to evaluate the efficiency and effectiveness of the proposed mechanism in malicious node identification and attack resistance. The results show that ET-DSR protocol selects trustworthy and energy based and improves the overall performance of the protocol in presence of malicious nodes.
