An Ad hoc network is subjected to many malicious activities and security threatens because of its wide distribution and heterogeneous nature. Intrusion is one among such activities that comprise confidentiality, integrity or availability of resources. Numerous efforts have been made in the literature to detect intrusion in an Ad hoc network, however less number of efforts have been put to construct an intrusion relieved network. In this paper, the authors proposed a methodology to construct an intrusion relieved network based on trust level of every node. The methodology used Rotboost algorithm to estimate the trust level of every node in the upcoming instants. As the learning of Rotboost requires more time, they planned to incorporate a fast learning algorithm to improve the efficiency of the methodology.
