An Optimal Risk- Aware Mechanism for Countering Routing Attacks in MANETs
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
Mobile Ad Hoc Networks (MANET) are a distributed and self configuring wireless networks. MANETs does not have a predefined network infrastructure. Application of MANET is benefited in areas such as disaster relief, military services and mine site operations. Each node communicates with the other acting nodes as routers. The co-operation and trust between the nodes are depended for the proper functioning of MANET. Being the flexible network, MANET is exposed to various types of attacks especially the routing attacks. There are various methods introduced to mitigate such critical routing attacks. In this paper, we propose a risk-aware response mechanism to systematically cope with the routing attacks in MANET, proposing an adaptive time-wise isolation method. Our risk-aware approach is based on the extended DempsterShafer (D-S) evidence model. D-S theory has been adopted as a valuable tool for evaluating the reliability and security in information systems and by other engineering fields, where precise measurement is impossible to obtain or expert elicitation is required.
