ABSTRACT
Sensor nodes in wireless sensor networks are easily exposed to open and unprotected regions. A security solution is strongly recommended to prevent networks against malicious attacks. Although many intrusion detection systems have been developed, most systems are difficult to implement for the sensor nodes owing to limited computation resources. To address this problem, we develop a novel distributed network intrusion detection system based on the Wu-Manber algorithm. In the proposed system, the algorithm is divided into two steps; the first step is dedicated to a sensor node, and the second step is assigned to a base station. In addition, the first step is modified to achieve efficient performance under limited computation resources. We conduct evaluations with random string sets and actual intrusion signatures to show the performance improvement of the proposed method. The proposed method achieves a speedup factor of 25.96 and reduces 43.94% of packet transmissions to the base station compared with the previously proposed method. The system achieves efficient utilization of the sensor nodes and provides a structural basis of cooperative systems among the sensors.

Mentions: Figure 2 shows an example of the system model based on the multiple networked sensors. Each node is assigned to certain regions and gathers external sensing information for predefined purposes. For a certain time period, the nodes have transmitted the data to the assigned base station for summarization of the sensing works. Meanwhile, the base station of a particular region is responsible for collecting data and managing sensors in the same region. The packet from each base station to a top monitoring server represents the summarized sensing data of their own regions. Because of this cluster-based structure, the general analysis at the top monitoring server is simplified by these base stations.
