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.
