Abstract 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. Keywords: Wireless Sensor Network, Centralized Intrusion Detection System _ Misuse Detection _______________________________________________________________________________________________________ I.
INTRODUCTION
Wireless Sensor Networks (WSNS) A wireless sensor network is an infrastructure consists of sensing, computing, and communication elements that gives the ability to instrument to an administrator, observe, and react to events and phenomena in a specified environment. WSN is a large array of diverse sensor nodes that are interconnected by a communication network. For a distributed estimated system, the sensing data are shared between the sensor nodes and are used as input. Reliability, Accuracy, Flexibility, Cost effectiveness, and Ease of deployment are the fundamental objectives for WSN. WSN is made up of individual multifunctional sensor nodes. Features of Wireless Sensor Networks Wireless sensor networks have various unique features that are listed below: Self-organizing Cooperation of sensor nodes Dynamically changing topology Short range communication and multihop routing Limited energy, computational power and memory Applications of Wireless Sensor Networks
