Cost Effective Routing Protocols Based on Two Hop Neighborhood Information (2NI) in Mobile Ad Hoc Networks
Ad hoc networks are collections of mobile nodes communicating with each other using wireless media without any fixed infrastructure. During both route discovery and traversal of route-reply packets from destination to source, broadcast of packets is required which incurs huge message cost. The present article deals with the message cost reduction during transmission of route-reply from destination to source. Also the redundancy that is visible within the 2-hop neighborhood of a node is minimized during broadcasting of route-reply. This improves the average lifetime of network nodes by decreasing the possibility of network partition. The scheme of 2NI can be used with any reactive routing protocol in MANETs.
