ANODR based anomaly detection for black hole and route disrupt attacks

An anonymous on demand routing protocol (ANODR) was designed based on the previous studies as the countermeasure for preventing passive attacks. ANODR is a purely on demand routing and identity free routing scheme that sets up an anonymous route as needed in real time. The proposed protocol ensures node privacy, route anonymity and location privacy and is robust against several known attacks. This limits the chances of eavesdropping and traffic analyzing to a time-critical on-demand window. Anonymity is one of the important characteristics in securing a wireless ad hoc network routing. In this paper we study the unique anonymity threats in wireless ad hoc environments. Two design principles of anonymous routing - anonymous route discovery and anonymous data forwarding are presented here. In the anonymous route discovery design, a random route pseudonym for an on demand route is established. In the anonymous data forwarding design, the source wraps its data packets for each end to end connection. This was implemented and tested using NS-2.0 simulator. The behavior of the proposed system has been studied for analysis like packet delivery ratio, packet delay and overhead along with the existing system.
