MANETs (Mobile Ad hoc NETworks) are de-centralized wireless networks with self-configuring mobile nodes. Due to the absence of trusted centralized authority or openness of network topology, these networks are susceptible to security threats. Black hole attack is one of the route disruption attacks that cause a greater damage to the network. In this attack, a malicious node belie that it is having shortest path and traps packets thereby degrading network performance. MANETs pose a greater challenge for routing protocols.
