A MANET is a self configuring infrastructure less networks. It is usually connected by wireless. Each device in a MANET is independently to move in any direction. To maintain neighbor position the geographic location coordinates of the node is a famous method used by most geographic routing protocol for the purpose of periodic broadcasting of beacon packets. If the location information is not available at the node then the geographic method is used. Based on the mobility dynamics of the node and the forwarding patterns, the Adaptiveb Position Update (APU) technique is used in the MANET. The location information update process is done by using NS2 simulations of geographic routing protocol.
