Abstract: The existing ad hoc routing protocols do not accommodate any security and are highly vulnerable to attacks. We discuss threats and attacks against ad hoc routing under several areas of application. A mobile ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies. The assumption of a trusted environment is not one that can be realistically expected; hence, several efforts have been made toward the design of a secure and robust routing protocol for ad hoc networks. We formulate the threat model for ad hoc routing and present several specific attacks that can target the operation of a protocol. MANET is an emerging research area with practical applications. However, wireless MANET is particularly vulnerable due to its fundamental characteristics, such as open medium, dynamic topology, distributed cooperation, and constrained capability. Routing plays an important role in the security of the entire network. In general, routing security in wireless MANETs appears to be a problem that is not trivial to solve. In this article we study the routing security issues of MANETs, and analyze in detail one type of attack — the “black hole” problem — that can easily be employed against the MANETs. We also propose a solution for the black hole problem for ad hoc on-demand distance vector routing protocol. Reason for this increased attention is the wide range of multimedia applications running in an infrastructure less environment. Because of the infrastructure less environment, limited power and dynamic topology it becomes very difficult to provide a secure environment in MANET. In this paper we are providing a detailed survey of different kind of attacks and proposed solutions for handling those attacks. This paper also gives a brief comparison of various protocols available for secured routing in MANET.
