In this paper, we measured multiple black hole attacks simultaneously in Network Simulator 2 (NS2) in terms of throughput, energy efficiency and data packet delivery. We also proposed a simple solution for detection and avoidance black hole attacks. Our simulation results show that the more attackable nodes in network simultaneously, the lower the energy efficiency network performance and if AODV routing protocol with detection and avoidance mechanism (dam) of black hole attack nodes is deployed in network, the performance of network can be better about 35% in comparison AODV without avoidance.
