In Mobile Ad hoc Networks (MANETs), nodes are capable of frequently changing their location. For effective routing, each and every node is expected to keep track of its moving neighborhood. So whenever the neighbor node changes, all the other nodes should update its routing table to invalidate the paths passing though old neighbors. This prevents the node from sending future packets to a node which is now not its neighbor, and thus preventing loss of packets. When network is highly dynamic neighborhood management becomes more important. Every node broadcasts a beacon, often known as HELLO packet, so that its neighbors may record its presence. Broadcasting HELLO packets consumes node energy. In this project work an alternative method for HELLO messaging is proposed to save energy and increase the throughput. Instead of constantly sending the hello packets to all the nodes for a specific time period. Otherwise to send the hello packets to the nodes which are in active state, this method conserves the energy, eliminating the hello packets to the broken links.
