A Review on Security Issues of Routing Protocols in Mobile Ad-Hoc Networks

A Mobile Ad Hoc Network (MANET) is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. There are a number of routing protocols developed by researchers. Due to the nature of ad hoc networks, secure routing is an important area of research in developing secure routing protocols. Although researchers have proposed several secure routing protocols, their resistance towards various types of security attacks and efficiency are primary points of concern in implementing these protocols. This paper presents some of the available secure routing protocols and most common attack patterns against ad hoc networks. Routing protocols are subjected to case studies against the most commonly identified attack patterns such as: denial-of-service attack, tunneling, spoofing, black hole attack and wormhole attack etc.
