The detection and defence of DoS attack for wireless sensor network
Due to the limitations of energy,computation and storage for sensors etc,although the wireless sensor networks (WSNs) have been widely deployed in many applications,it is a critical challenge to present the effective and lightweight security protocol to prevent various attacks for WSN,especially for the denial of service (DoS) attack.Normally,the adversaries compromise sensors and launch the DoS attack by replaying redundant messages or making overdose of fake messages.In this paper,we design a novel message observation mechanism (MoM) to detect and defense the DoS attack.Based on the spatiotemporal correlation,MoM utilizes the similarity function to identify the content attack as well as the frequency attack.And then the MoM adopts rekey and reronte countermeasures to isolate the malicious node.The security analysis shows that our solution can not only detect and defense the DoS attack but also can reduce the energy consumption.
