摘要：An Ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. In Mobile Ad-hoc Networks (MANET), each mobile node acts as a host as well as a router. These nodes communicate to each other by hop-to-hop communication. The dynamic topology of MANET allows nodes to join and leave the network at any point of time. Wireless MANET is particularly vulnerable due to its fundamental characteristics such as open medium, dynamic topology, distributed cooperation and constrained capability. So security in MANET is a complex issue. There are a lot of routing protocol for Ad-hoc network like Ad-hoc On Demand Distance Vector Routing (AODV), Dynamic Source Routing (DSR), Destination Sequence Distance Vector Routing (DSDV) and Temporally Ordered Routing Algorithm.AODV is an on-demand reactive routing protocol for mobile ad hoc networks. But in existing AODV, there is no security provision against a well-known "Black Hole" attack. Black Hole nodes are those malicious nodes that agree to forward packet to destination but do not forward packet intentionally. These Black Hole nodes participate in the network actively and degrade the performance of network. In this paper we proposed a solution for identifying the malicious node in AODV protocol suffering from Black Hole attack.
