Survey on Secure Routing in Mobile Ad-hoc Networks

Wireless networks are widely deployed in the present scenario. A type of wireless network, mobile ad hoc network (MANET) is an autonomous system of mobile nodes where a collection of mobile hosts with wireless network interfaces form a temporary network without the aid of any fixed infrastructure or centralized administration. The success of MANET strongly depends on its security. Security is an essential service for wireless network communications especially in mission-critical applications like military applications. A variety of attacks such as Warmhole, Blackhole, Byzantine, Rushing/Flooding, Anonymity/Location Disclosure, Denial of Service etc have been identified and some solutions have been proposed in the literature. However, existing published solutions typically concentrate on particular type of attacks and are incapable of identifying threats, which occur as a result of combination of these attacks. As overall security level is determined by the system's weakest point, a distributed security scheme that uses an integrated approach to address a combination of these attacks is very much necessary. The work in progress aims to investigate the possible combination of attacks that can be addressed by integrating some of the existing work on mobile ad hoc networks security, which addresses a portion of the security concerns individually. The analysis of attacks and existing mechanisms that would help to design an integrated approach for security services is presented in this paper.
