Improving the Performance of AODV by Minimizing Flooding Through High Power Routing Node
Broadcasting has been used widely in wired and wireless networks to understand the data and topology information. There are various routing protocols in MANETs rely on a flooding mechanism to broadcast data and control packets over the entire network for establishing routes between source destination pair. The simplest way of broadcasting a packet to all nodes in the network is basic flooding or blind flooding which allows each node to retransmit a packet to its neighbours, in case it has not received broadcast packet during earlier transmission. This work proposes a modified version of AODV termed as AODV_HPR where certain nodes are assumed to be high energy transmission nodes known as High Power Routing (HPR) nodes, utilized for routing. The route is established only through HPR nodes which are capable of communicating to long distance.
