Intrusion Response with Dempster Shafer theory of evidence to detect and overcome routing attack in Mobile Ad hoc Networks

Mobile Ad hoc Networks are extremely exposed to attacks because of the self-motivated nature of its network infrastructure. Out of all these attacks, routing attacks need sizeable attention since it could root the most upsetting harm to MANET. There exist several intrusion response techniques to mitigate such critical attacks, still the existing solutions typically attempt to isolate malicious node based on immature unclear response decisions. However these responses may consequence in the unforeseen network separation, causing supplementary damages to the network infrastructure, and also could lead to ambiguity in countering routing attacks in MANET. In this paper an intrusion response mechanism is proposed to thoroughly deal with the recognized routing attacks. This approach is based on an extended Dempster-Shafer mathematical theory of evidence with belief of value factors. Also result shows the helpfulness
