Analysis of energy efficient, LEACH-based cooperative wireless sensor network

Abstract

Energy efficient transmission is the foundation for energy efficient communication. Similarly, for (Wireless Sensor Network) WSN energy efficiency is of prime importance because of its constrained size that results in constrained battery. The transmission medium being wireless, fading plays a major role on the performance of WSN. It detoriates the overall performance which leads to indirect consumption of battery of a sensor node. Cooperative communication combats fading and saves energy of a network. In this paper application of cooperative communication has been implemented and analyzed. Experimental results show that when cooperation is there the total energy consumed by the WSN is much less than the energy consumed by the WSN without cooperation. Cooperation makes WSN more energy efficient. It is a known fact that wireless transmission is energy consuming operation. LEACH is considered as most popular routing protocol which has better performance in saving the energy consumption. It is implemented in cooperative WSN and experimental results show that LEACH makes cooperative WSN more energy efficient.
