Investigation and Optimization of Hello Message Interval for Scalable Ad-Hoc Network

Mobile A d h o c Networks (MANET) has become an exciting and important technology in recent years because of the rapid proliferation of wireless devices. A mobile ad-hoc network alive of mobile nodes that can move freely in an open environment. Communicating nodes in a MANET usually seek the help of other intermediate nodes to establish communication channels. manet contain reactive protocols Aodv is one of popular protocol. Route failure due to motion of nodes and lack of battery power thus route maintance is an important issue.routing is an important function aspect in wireless ad-hoc network that handles discovering and maintaining the path beween nodes within a network.For route maintance the node periodically broadcast hello message to their neighbours.In aodv although benefits of these messages have been proven,many study show some drawback for these message.In paper we optimize the hello interval with different hello loss 2 or 3.The simulation is done on Qualnet.Result analysis determine that Aodv perform better at HI=3 se
