ABSTRACT:
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. So that our proposed scheme has three techniques based on hop count, decision anomaly, neighbor list count methods are combined to detect and
isolate wormhole attacks in ad hoc networks. That manages how the nodes are going to behave and which to route the packets in secured way.
