SG-AODV: Smart and Goal Based AODV for Routing in Mobile Ad hoc Networks

A mobile ad hoc network is a continuously self-configuring, infrastructure-less network of mobile devices connected without wires. As nodes are mobile in this network, routing is an important challenge. In this paper, we proposed new intelligent algorithm (SG-AODV) for routing to improve AODV routing protocol. In proposed algorithm, scores are considered for nodes according to energy of nodes, congestion in the routing queue of nodes and link states. Algorithm uses scores for selecting best rout and chooses rout with highest score as main route and rest of discovered routs are stored in temporal memory or cache of nodes to use them if main route is damaged or interrupted. SG-AODV is implemented in NS2 simulator and results show proposed algorithm improves the delay of sent packets, routing overhead and delivered packets of AODV protocol.
