An overview on: Intrusion detection system with secure hybrid mechanism in wireless sensor network

Wireless Sensor Networking is one of the most important technologies that have different applications. The security of wireless sensor networks is a big concern. Hence for secure communication it is important to detect and prevent the attacks in network. Major focus is given on security and on detection and prevention of attacks. Adversary can create gray-hole attack and black-hole attack simultaneously; there are many methods which do not provide proper method to defend against these kinds of attacks. The Ad-hoc On Demand Distance Vector (AODV) scheme is used for detecting Gray-Hole attack and Enhanced Adaptive Acknowledgment (EAACK) mechanism is used for detecting black-hole attack in network. But only by detecting and preventing the attacks, it does not provide the better security to wireless network. Therefore, to secure network a hybrid mechanism is deployed in wireless sensor network. Security algorithm for wireless sensor networks such as CAWS and Modern Encryption Standard (MES-1) is used for secure communication. The CAWS and Modern Encryption Standard (MES-1) is an advanced cryptography method which is used for encryption and decryption process to provide special security. This paper focuses on strong security by detecting and preventing attacks, also ensures data authentication, integrity of data and solves less power transmission of data and receiver collision problem, by deploying hybrid mechanism.
