Types of Flooding Attacks in MANET

Abstract

The Mobile Ad-Hoc Network (MANET) is open, infrastructure-less wireless network which composes a set of mobile, decentralize and self organized nodes. In MANET each node has the freedom to connect with other nodes, to leave that node and to move freely in the network. As the mobile ad-hoc network has no fixed infrastructure or it is a central administration, the relative communication issues arrived in network are more complex as compared to cellular network. In that case as the nodes in the mobile ad hoc network any type of secure protection, it has no physical protection for unaware attacks. Hence the node of the mobile ad-hoc network is easily influenced by any type of networking attacks. The nodes are particularly to be exposed by denial of service (DOS) attacks which are launched through unauthorized disclosure. The new DOS attack, called Ad-Hoc Flooding Attack (AHFA), can result in denial of service when used against on-demand routing protocols for mobile ad hoc networks, such as AODV, DSR. The intruder transmits all data packets to drain the communication bandwidth and node information, so that valid communication cannot establish over the network.

In this paper we are discussing about flooding attacks and other attacks which may harm the network by their presence in the network. So we continue to detect such types of flooding attacks in MANET.
