Performance Improvement in Adaptive Routing Strategy in Mobile Adhoc Network

It has been a big challenge to develop a routing protocol that can meet different application needs and optimize routing paths according to the topology change in mobile adhoc networks. Based on their forwarding decisions only on the local topology, geographic routing protocols have drawn a lot of attention in recent years. In routing, nodes need to maintain up-to-date status of their immediate neighbors for making effective forwarding decisions. The periodic broadcasting of beacon packets that contain the geographical location coordinates of the nodes is a popular method used by most routing protocols to maintain neighbor status. Each node can determine and adjust the protocol parameter values independently according to different network environments, data traffic conditions and nodes own requirements. The project offers the Adaptive Status Update strategy for routing, which dynamically adjusts the frequency of status updates based on the mobility dynamics of the guests and the forwarding patterns in the network based on nodes whose movements are harder to predict update their status more frequently, and nodes closer to forwarding paths update their Status more frequently.
