The term MANET (Mobile Ad-hoc NETwork) refers to a multi-hop packet based wireless network composed of a set of mobile nodes that can communicate and move at the same time, without using any kind of fixed wired infrastructure. In mobile ad-hoc networks the geographic routing protocol has high priority. This routing protocol maintains the nodes nearest to destination. It requires information about final destination of a packet and neighbor node positions. For maintaining the node updates a unique strategy is used known as Adaptive Position Update (APU). It uses two principles: nodes whose moments are harder to predict & closer to forwarding paths are updated frequently.
