摘要 为了从系统层面提高网络能效,需要计算网络整体能耗,分析影响能耗的关键因素,从而进行网络优化。为此,从分析全网数据流转时的节点状态出发,提出了一种基于网络容量估算无线传感器网络能耗上限的能量模型,并利用此模型进行了链式结构的路由优化设计。研究结果表明,该模型对于无分级的宽放型网络结构具有普遍适用性。 Computing the whole energy consumption of wireless sensor networks, analyzing the key factors of influencing the energy efficiency, and then optimizing the energy efficiency of networks are necessary to improve the whole energy efficiency. An energy model to evaluate the upper bound of energy consumption in wireless sensor networks based on the capacity of networks is proposed, beginning with analyzing the nodes' status in data transferring. The optimum routing design for the network of link architecture is implemented using this model.
