Research on intrusion detection system based on security protocol for wireless sensor networks

By analyzing the difference of intrusion detection between WSNs based on-demand and traditional networks, this paper proposed intrusion detection system based on security protocol for WSNs according to the network feature, which was called SPIDS. SPIDS made full use of the detecting function and power resource in base station, and increased the real-time detection accuracy to malicious nodes depending on the feature of security protocol and the routing topology information. Simulation results show that SPIDS can effectively resist some typical attacks, and improve the security performance for WSNs.
