Review- Energy Efficient Data Transmission over Wireless Network for Control System

Transmission energy management is a key issue to optimize the life-time operation of the overall wireless network. However, designing a communication protocol for wireless networked control system brings the additional challenge of guaranteed stability as compared to traditional wireless sensor network. The motivation of this paper is to minimize the energy consumption of the communication system where nodes are operated on batteries. . The total energy consumption includes both the transmission energy and the circuit energy consumption. By using novel algorithm that assigns communication radii to sensors as a function of their load. We show via both analysis and simulation that our algorithm, which utilizes shorter transmission ranges for heavily loaded sensors and larger transmission ranges for lightly loaded sensors, is about 50% more energy efficient than schemes utilizing a fixed transmission radius for every sensor. We also show that our algorithm obtains a 95% improvement as compared to the case of a stationary base station
