摘要：Wireless Sensor Network (WSN), consists of a large number of sensor nodes. E ach sensor node senses environmental phenomenon and sends the sensed data to a sink node. Since the sensor nodes are powered by limited power batteries. Energy efficiency is a major challenge in WSN applications. In this paper, we propose an analytical model for energy consumption estimation in clustered WSNs using M/M/1 queuing model. The model can be used to investigate the network performance in terms of average energy consumption. We also propose a power minimization scheme to reduce energy consumption of sensor nodes by reducing the number of transitions between the idle and active states of sensor nodes according to the number of data packets in the queue. Our analytical model, based on the main parameters such as the average energy consumption and the number of packets (jobs), significantly reduces energy consumption. Simulation, support the validity of the proposed approach.
