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, the authors propose a risk-aware response mechanism to systematically cope with the routing attacks in MANET, proposing an adaptive time-wise isolation method.
