本文主张使用新兴的分布式压缩感知（DCS）范例，以部署能量收集（EH）无线传感器网络（WSN），其实际网络寿命和数据收集速率远远高于最先进的水平。特别是，我们认为EH WSN中有两个基本机制：i）与EH过程相关联的能量多样性，其使得所收集的能量可以在传感器节点之间变化，（二）与DCS过程相关联的感测多样性使得能量消耗也可以在传感器节点之间变化，危及数据恢复。我们还认为，这样的机制提供了一种手段，以密切匹配的能源需求的能源供应，以解锁能量中立的无线传感器网络，利用EH能力的可能性。一些分析和仿真结果，以说明该方法的潜力。
This paper advocates the use of the emerging distributed compressive sensing (DCS) paradigm in order to deploy energy harvesting (EH) wireless sensor networks (WSN) with practical network lifetime and data gathering rates that are substantially higher than the state-of-the-art. In particular, we argue that there are two fundamental mechanisms in an EH WSN: i) the energy diversity associated with the EH process that entails that the harvested energy can vary from sensor node to sensor node, and ii) the sensing diversity associated with the DCS process that entails that the energy consumption can also vary across the sensor nodes without compromising data recovery. We also argue that such mechanisms offer the means to match closely the energy demand to the energy supply in order to unlock the possibility for energy-neutral WSNs that leverage EH capability. A number of analytic and simulation results are presented in order to illustrate the potential of the approach.
