    Compromising AODV for better performance
    (Faculty of Graduate Studies and Research, 2017-01-26) Jayakody, A.; Paranavithana, P.
    MANETs became a principal research area as a promising routing protocol for a large scale of applications, due to its' behavior of self-configuring ability according to the infrastructure. Energy efficient in MANETs is a significant area in MANETs related researchers. Nodes in a MANET networks are basically battery operated, and thus have access to a limited amount of energy. The lack of energy can lead to a link failure during an active communication session, which affects the throughput and energy wastage due to a re-run of the algorithm. These papers presents a modified AODV algorithm, where a node calculates its residual energy and select the best path based on the existing matrices and total energy of the path. During the RREQ packet exchange, each node adds its residual energy to the packet and forwards it until it reaches the destination. At the destination, the total energy value is copied to the RREP packet from RREQ packet and sent to the source node through the reverse path. During the process of route selection, the path with the highest energy value gets the priority.
