Abstract

A MANET is a type of ad hoc network that can change locations and configure itself on the fly. Because MANETS are mobile, they use wireless connections to connect to various networks. MANET is group of large independent wire nodes interconnecting each other on peer to peer basis in an environment without any infrastructures. There are different attacks against the routing protocol in ad hoc networks. These attacks may have the aim of modifying the routing protocol so that traffic flows through a specific node controlled by the attacker. An attack may also aim at impeding the formation of the network, making legitimate nodes store incorrect routes, and more generally at perturbing the network topology. In this paper analysis, different type of black and gray hole attack detection techniques and algorithms in existing paper. A packet drop attack or blackhole attack is a type of denial-of-service attack in which a router that is supposed to relay packets instead discards them. The malicious router can also accomplish this attack selectively, e.g. by dropping packets for a particular network destination, at a certain time of the day, a packet every n packets or every t seconds, or a randomly selected portion of the packets. This is rather called a greyhound attack. If the malicious router attempts to drop all packets that come in, the attack can actually be discovered fairly quickly through common networking tools such as traceroute. Also, when other routers notice that the compromised router is dropping all traffic, they will generally begin to remove that router from their forwarding tables and eventually no traffic will flow to the attack. In this paper a survey on different detection and prevention techniques for the black hole and gray attack in MANET is presented.
