Anomaly detection for DOS routing attack by a attack source location method

We consider a credible routing in Ad Hoc network for DOS attack problems. This paper presents a probabilistic packet marking location technology, describes the source packet marking attack node localization method, and here we build the attack source reliable positioning model based on probabilistic packet marking. In this case, we provide that the data source in Ad Hoc network can back and transmission path can restore, it can be tracked by some behavior of the network user node, information of the sender, forwarding and receiver can deny that the occurrence of data exchange. We also verified the relationship between the success rate of packet marking probability and location. The simulation results show that this method is found in destination node after the DOS attack can date back to the location of the attack source actively.
