Security Aspects in Ad Hoc Network Routing

The authors have presented here some security aspects related to the routing protocols for Mobile Ad hoc NETworks (MANETs). A mobile ad-hoc network is a self-configuring network of mobile routers, connected by wireless links, which are free to move randomly and organize themselves arbitrarily. These types of networks operate in the absence of any fixed infrastructure which makes them easy to deploy but it becomes difficult to make use of the existing routing techniques for network services. This poses a number of challenges in ensuring the security of the communication. Because of the changing topology special routing protocols have been proposed to face the routing problem in MANETs.
