A mobile network is having number of security challenges because of its public access communication. One of such challenge is black hole attack. A black hole node receives the packets from the sender forcefully and did not forward it to the destination. This attack becomes more challenging when more than one black hole attacks perform communication in cooperation. The cooperative black hole attack cannot be resolved by tracking a single node communication. In this work, a statistical analysis on all nodes is applied under different parameters to identify all cooperative nodes based on non cooperating behavior with other nodes.
