摘要：In recent years, energy efficiency and data aggregation is a major concern in many applications of Wireless Sensor Networks (WSNs).WSNs, consists of a large number of sensor nodes. Each sensor node senses environmental phenomenon and sends the report to a sink node. Since the sensor nodes are powered by limited power batteries, so energy efficiency is a major challenge in WSNs applications. For this purpose, many novel innovative techniques are required to improve the energy efficiency. Data aggregation is one of the most important issues for achieving energy-efficiency in WSNs. The main goal of data aggregation is decreasing energy consumption by decreasing need for redundant data transmission. In this paper, we propose an analytical model for evaluating energy consumption in term of data transmission, reception and aggregation in cluster based WSNs architecture using M/M/1 queuing model. Analysis support the validity of the proposed approach networks with compare the energy consumption results for networks with and without data aggregation technique
