An Energy Efficient Secure Acknowledgement based Authentication Protocol for WSN

Since last few years migration from wired networks to wireless networks is the global trend. This wireless network should be secure and it should have a good lifetime. If the system is not secure or if it does not have a good lifetime, it becomes really costly to maintain wireless network. There are two main functions to enhance the lifetime of a wireless network i. e. clustering and detection of intrusions. We cluster a few nodes to enhance the life efficiency and the node with the highest energy is used for communication. For security, a number of intrusion detection techniques are applied. In this paper we will discuss about multiple clustering and intrusion techniques.
