In mobile ad hoc networks the nodes are dynamically changing and they have a fully decentralized topology. Hence, security is hard to achieve due to the dynamic nature of the relationships between the participating nodes as well as the vulnerabilities and limitations of the wireless transmissions medium. We proposed a novel agent based framework to monitor, detect, and isolate misbehaving nodes in the MANET. The proposed framework protect both routing and data forwarding operations, which aiming at improving the efficiency in detecting and isolating misbehaving nodes with a minimum overhead. In this paper local neighboring nodes collaboratively monitor each other. A novel honesty rate strategy is introduced in each node to determine the well-behaving nodes. We evaluate through network simulations the effectiveness of the framework in detecting malicious nodes and improving the network performance.
