An Approach for Geographical Routing in MANET
Prajakta Deshbhratar, Monika Chvhan · 2014
Geographic routing is a routing principle that relies on geographic position information. It is mainly proposed for wireless networks and based on the idea that the source sends a message to the geographic location of the destination instead of using the network address. In geographic routing, nodes need to maintain up-to-date positions of their immediate neighbors for making effective forwarding decisions. Periodic broadcasting of beacon packets that contain the geographic location coordinates of the nodes is a popular method used by most geographic routing protocols to maintain neighbor positions. Adaptive Position Update (APU) strategy for geographic routing, which dynamically adjusts the frequency of position updates based on the mobility dynamics of the nodes and the forwarding patterns in the network. In this paper we mainly proposed for wireless networks and based on the idea that the source sends a message to the geographic location of the destination instead of using the network address. The benefits of APU are confirmed by undertaking evaluations in realistic network scenarios, which account for localization error, realistic radio propagation, and sparse network. . In this paper we systematize the knowledge about the geographical routing and explain about how various parameters are executes using various techniques.
