EigenTrust-based non-cooperative game model assisting ACO look-ahead secure routing against selfishness

Abstract

In mobile ad hoc networks (MANETs), selfish behavior is observed when nodes fail to forward data packets which are actually intended. This is generally assumed to be a kind misbehavior which might interrupt the network operations. Here, we propose a QoSconstrained EigenTrust-based non-cooperative game model for secure fault-tolerant ant lookahead routing which attempts to identify trusted valid route and look-ahead route pairs which might help in choosing the alternate path in case of valid route failure. Simulation results illustrate that the proposed trust-based secure routing is able to accurately distinguish malicious nodes from good nodes with a limited overhead. © 2014 Subbaraj and Sabarimuthu.
