Tees-two-tier energy efficient secure scheme for increased network performance in wireless sensor networks

Security and energy are two most aspect in WSN. The privacy is also significant features in wireless sensor network (WSN). We have many security routing protocols in wireless sensor network. But the main goal is to provide security with less energy consumption. This paper we are going to demonstrate energy efficiency and security scheme in contradiction of power draining occurrence especially renunciation of sleep attack, replay and forge attack. All these attack are going to shorten the life time of sensors in WSN. We are going to develop a "Two Tier Energy Efficient Secure Scheme" (TE2S) incorporating MAC protocol. This scheme decrease authenticating procedure as short as conceivable to reduce the power draining effect TE2S scheme will have same throughput with less energy consumption.
