Design and Simulation of Intrusion Detection Based on DSR Protocol

Security of Mobile Ad hoc network is much more important due to its public transmission media,dynamic topology,cooperative route algorithm,lack of monitoring and managing and etc.Now three kinds of Intrusion nodes are defined: to minimize the spense of energe,Selfish node would skip the responsibility of a router;Black hole nodes which are eager to play the router role in order to discard the useful data packet;Faulty node does not forward or pop up packets due to software or hardware fault.The aim is to simulate the malicious nodes' behavior on NS2,and then add the function of monitoring to the DSR routing protocol,compare the results with and without the monitor system.The result shows that the monitor system turns down the packet loss ratio and gets the increase of average route hop under control.
