ANT Based Trustworthy Routing in Mobile Ad Hoc Networks Spotlighting Quality of Service

Mobile ad hoc network (MANET) is a impartial network capable of sovereign operation where nodes communicate with each other without the need of any obtainable infrastructure. Nodes are mobile since topology is very dynamic and are often vulnerable to failure thus making mobile ad hoc networks open to threats and attacks. Nodes sometimes fail to transmit and start dropping packets during the transmission. Such nodes are responsible for untrustworthy routing. Natureinspired algorithms (swarm intelligence) such as ant colony optimization (ACO) algorithms have shown to be a good technique for developing routing algorithms for MANETs. In this paper An ANT based trusted AODV is presented. Trust is introduced and nodes are considered for routing only if they have trust level higher than the threshold).Ant optimization is implemented to increase the optimization of MANET routing. The proposed protocol increases PDR and decreases delay thereby enhancing the QoS metrics and trustworthiness in AODV based MANET routing. The work is implemented and simulated on NS-2. The simulation result shows the proposed AODV provides more trustworthy and optimized routing compared with general AODV.
