A rule based mechanism to mitigate the packet dropping in blackhole attack.

Aodv ns-2.34 pdr

Wireless ad hoc network is extensively used area for research work nowadays because of its dynamic and infrastructure less behavior. But due to such characteristic it is more vulnerable to severe kind of security threats which can theft or break our security system and stop services used for communication. Among various kinds of attacks one of attack is black hole which inject false route and announces itself as it has fresh and shortest route to deliver the packet. The wireless network uses routing protocol to route the packet from source to destination. In this we use rule based approach to detect black hole node by using the retransmitting and time varying mechanism. The proposed method is simulated in NS2.34 network simulation tools and the analysis of the proposed work is done using performance metric like PDR, end to end delay and routing load etc.
