Efficient Routing in Mobile Adhoc Networks Emphasizing Quality of Service by Trust & Energy based AODVPublished online: Mar 23, 2015
Attention in the region of Mobile Ad-hoc Network (MANET) is increasing because of its realistic applications and necessity of communication in mobile devices. A mobile ad hoc network consists of mobile self configuring wireless nodes and these nodes communicate between them without any centralized management. The dynamic characteristics of MANET, has made it fairly demanding to uphold connectivity and guarantee Quality of Service (QoS). The trust based routing is one way to form cooperation among nodes for performing an efficient routing between nodes. In this paper a trust and energy based AODV is presented where nodes are selected for routing based on its trust and energy value. Trust is calculated based on the nodes success and failure rate. Energy calculated based on consumed and remaining energy values. A threshold value is defined and nodes are preferred for routing only if its trust and energy levels are higher than threshold. The work is implemented and simulated on NS-2. The simulation results have shown improvement on QoS metrics when compared with traditional AODV and DSR.
