Distributed intrusion detection system for sensor networks

An intruder tries to disable the single point in a network, i.e. the central analyzer. If this is disabled, the entire network is without protection. Since the sensor nodes fail often, the use of a centralized analyzer is highly limited. Processing all the information at a single host implies a limit on the size of the network that can be monitored. Because of the limit of the central analyzer, it is difficult to keep up with the flow of information in large network like sensor. We have proposed distributed intrusion detection system for distribute sensor networks.
