Dynamic Power Control With Energy Constraint for Multimedia Wireless Sensor Networks

In recent years, many approaches and techniques have been explored for the optimization of energy usage in Wireless Sensor Networks (WSN). It is well recognized that a proper energy consumption model is the foundation for developing and evaluating a power management scheme in WSN. In this paper, the authors propose a new complete information Markov Decision Process (MDP) model to characterize sensors energy levels. They also propose and compare several centralized power control policies to select the more efficient policy that optimizes throughput and energy consumption.
