Abstract
There can be several sophisticated attacks motivated by selfish, resource saving nature of nodes in a civilian co-operation based ad-hoc network. Distributed rating model based castigation can be useful to discourage selfish nodes from performing these attacks. Even if an attacker is detected, it is hard to charge an accused node in a dynamic environment of an ad-hoc network. In this paper we detect a large range of attacks on dynamic source routing (DSR) protocol and the originator of the attack. We provide a mechanism to inform other nodes of the system about the accused, provide a context aware inference scheme to blame the accused and malicious accuser without doubt. We achieve this with minimal extension of DSR and in a cost effective manner.
