The Approach for the Prevention of Black Hole Attack in MANET using DSR Protocol and Ant Colony Optimization Technique: A Review

Ad Hoc Networks (MANETs) are self-organized network where nodes are free to move in any direction. MANET doesn't need any centralized system. Due to its dynamicity, Black hole attack is a serious security issue to be resolved. It takes place when a malicious node called as black hole enters into the network. Black hole node shows its fake behaviour during the process of route discovery. Today, many prevention techniques have been proposed for MANET. However, in the presence of fake nodes, the networks are subjected to different kinds of attacks. In this problem, a fake node advertises itself of having a shortest path to another node whose packets the fake node want to drop. In this flooding process, if the reply from the actual node reaches later than the fake node reply as requested by the main node. A forging path is created via a fake node. An ideal path is one in which the packet reach to destination with minimum delay and lesser overhead. In this paper we apply Dynamic Source Routing (DSR) protocol in order to prevent black hole attack using Ant Colony Optimization.
