Executive Summary

The infrastructure of a Mobile Ad hoc NETwork (MANET) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. However, almost all common routing protocols at present consider performance as first priority, and have little defense capability against the malicious nodes. Many researches have proposed various protocols of higher safety to defend against attacks; however, each has specific defense objects, and is unable to defend against particular attacks. Of all the types of attacks, the wormhole attack poses the greatest threat and is very difficult to prevent; therefore, this paper focuses on the wormhole attack, by combing three techniques.
