A Secure and Efficient Routing Mechanism for Intrusion Prevention in Wireless Sensor Network

The security attacks are common in WSNs because of less availability of the resources and harsh environment. Intrusion detection and prevention of these attacks are necessary. Aim is to achieve an intrusion detection system which is energy efficient. The objective is to detect and prevent security attacks, to reduce the communication overhead and consumption of energy in wireless sensor network. The Network layers attacks are wormhole attack, Sybil attack and selective forwarding attack. These attacks are overcome by symmetric key encryption where security is achieved in the sensor networks. The proposed method is an energy efficient routing method in an environment where detection and prevention intrusion schemes are used in wireless sensor network. The result shows the efficient consumption of energy. The simulation results are shown in NS-2 which shows the comparison with AODV routing protocol by considering parameters like energy and communication overhead.
