  3. Abstract:
  4. Wireless ad hoc networks are vulnerable against many types of attacks including black hole. In this paper we investigate the effect of this attack on ad hoc networks. Furthermore, we use hash chain to prevent this type of attack in a network that uses AODV as a routing protocol and results of applying this method has been investigated. Simulation results using OPNET simulator indicates that packet delivery ratio, in the presence of malicious nodes, reduces remarkably and proposed approach can prevent the effect of black hole attacks
