1.1 Introduction
1.1.1 What is MANET?
The term MANET (Mobile Ad-hoc Network) refers to a multi hop packet based wireless network consists set of mobile nodes used to transfer the related information and move without using any system structure. It is able to change the networks and doesn’t need any structure to maintain the data. It uses wireless connections to connect to various networks because they are mobile. The connections may be done through Wi-Fi connection, or another medium, such as a cellular or satellite transmission. Figure 1.1.1 Structure of MANET
1.1.2 How MANET Works?
The main functioning of MANET’s is to determine the properties of IP routing protocol functionality which are suitable for wireless

 The results show that APU can change related to the mobility conditions.APU generates less amount of beacon overhead when compared to other updating schemes but achieve better performance in terms of packet delivery ratio, average end-to-end delay and energy consumption. The performance of APU is evaluated using the real-world effects in the second set of simulations.
 Proposed scheme is proved as the best scheme over other updating schemes. Beacons generated in proposed system are more concentrated along the routing paths. In proposed scheme updated view technology is maintained which increases the performance.

1.5 OBJECTIVES
 The update policy used in proposed system is adapted to the mobility conditions.
 The accuracy of the locations and the updated intervals are calculated/find out using the proposed scheme better than the periodic beaconing.
 Using ODL rule, accurate view of the local network by the nodes along the data forwarding path through the exchange of beacons in response to data packets that are overheard from new
