Improved Adaptive Position Update for Geographic Routing in Mobile Ad Hoc Networks
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 5
Abstract
In geographic routing, the nodes ought to maintain up-to-date positions of their immediate neighbors. Periodic broadcasting of beacon packets that contain the geographic location coordinates of the nodes may be a new technique utilized by most geographic routing protocols to keep up neighbor positions. The traditional routing schemes demonstrate that periodic beaconing regardless of the node mobility and traffic patterns in the network are not attractive from both update cost and routing performance point of view. Since the Adaptive Position Update (APU) strategy for geographic routing, which energetically regulates the frequency of position updates based on the mobility dynamics of the nodes and the forwarding patterns in the network. Generally in Mobile Ad Hoc Networks, if forwarding nodes have high mobility then it may have many chances to make local topology inaccurate in nature. Hence this new Improved Adaptive Position Update (IAPU) technique for Geographic routing mainly enhances the APU with low mobility based forwarding node selection. This overcomes the link failure of the entire network in high mobility routing. Thus the experimental results exemplifies that the proposed approach drastically improves the performance of the existing APU.
