In MANET, mobile nodes are prone to various security attacks due to their dynamic changing topology, open medium and are constrained by limited energy, bandwidth and computational power. Most of the currently existing security algorithms designed for these MANETs are insecure, inefficient, and have low detection accuracy for nodes misbehavior. A novel trust based Certificate Authority concept is introduced to transmit data packets only through trusted nodes and isolate malicious nodes in the MANET. The proposed trust management scheme incorporates battery power consumption and packet integrity aspect in addition to direct and indirect trust values. Experimental results are presented with Qualnet Simulator 5.0. The proposed framework has shown better results in detecting malicious nodes and building a secure network.
