Trust Based Power Aware Secure Source Routing Protocol using Fuzzy Logic for Mobile Adhoc Networks

摘要

Secure transmission without node failure in Mobile Ad hoc Network is a challenging issue because of the absence of centralized administration, openness in the network topology and limited batter power in the nodes. In order to enhance the security of network and protect the nodes from vulnerabilities, this paper proposes a novel trust based power aware routing scheme which uses fuzzy logic prediction rules to select the most trustable path. 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 battery power. 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 Trust based Power Aware DSR routing protocol (FTP-DSR), provides a flexible and feasible method to choose the route that meets the security requirement of data packets transmission. 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 FTP-DSR improves packet delivery ratio and reduces average end-to-end latency when compared to the standard DSR routing.
