Wireless sensor networks have emerged a wide application for monitoring physical environment. Energy efficiency, Processing capability and communication range are the limitations of sensor networks. Moreover, the wireless networks are vulnerable to certain types of network attacks. One of them is the hello flood attack, in which a non- legal node in the network can flood hello requests to the legitimate nodes and break the security of WSN. The solutions for these types of attacks are mainly cryptographic that suffers from heavy computational complexity. Hence, they are less suitable for wireless sensor networks. In this paper, a new centralized intrusion detection system is proposed to detect and prevent hello flood attacks in cluster-based wireless sensors networks. The main idea of using centralized detection scheme, in which the base station decides on potential intrusions based on the control packets that are being sent from the cluster heads. The proposed energy efficient and simple intrusion detection technique is thus suitable for sensor nodes with resource constrained. Moreso, the simulation result confirms the expected performance of the proposed intrusion detection system in the terms of security and energy efficiency.
