Abstract: Threat of attacks on mobile nodes is increasing because of infrastructure less network in Mobile Ad Hoc Networks (MANETs). Black hole attack is a threat where malicious node fallaciously advertises or broadcasts the good path to the node falsely during the route-establishment process to the destination node. When a request is received by the attacker to the destination node for a route it creates a reply for the short route and enters into the passageway to do something with the packets passing between them. If the Black Hole Node is present in the network, it will reduce the network performance along with the depletion of the energy in the network. The source node sends the data packet to the destination, the malicious node drops all packets intended for forwarding. The Ad-Hoc On Demand Distance Vector (AODV) routing protocol is used in the existing system to detect black hole attack. If a path identifies that it has a malicious node then the data packets are forwarded in the next best shortest path. Although it chooses the alternative path the data packets will be transferred with the constant bit rate which leads to delay in the network there by decreasing the performance.
Keywords: Contention Window (CW), Ad-Hoc On Demand Distance Vector (AODV), Mobile Ad-Hoc Networks (MANETs), Packet Delivery Ratio (PDR).
