有了永生的承诺，能量收集和无线能量传输已经成为普适计算和网络的下一个研究前沿。挑战仍然是适应传感系统（传感、计算、通信）各个方面的操作，以处理这种能源的变化、不可预测或可能间歇性的供应。为了理解这些挑战，我们目前缺乏足够的工具来评估不同的能量收集和转移模型的影响——由于大规模部署此类系统的高成本，这进一步加剧了这种影响。我们提出了一个通用的，基于tossim的仿真框架来模拟能量收集和能量传输，使收集和传输感知应用程序，协议和系统软件的快速开发成为可能。我们的评估表明，即使是抽象的仿真模型也可以提供独特的见解，例如由于间歇性能源供应导致的频繁停电和节点重启。基于这些见解，我们通过展示高级模拟如何导致更好的能源调度算法选择，进一步建立该框架的实用性。
With the promise of delivering immortality, energy harvesting and wireless energy transfer have become the next research frontier for pervasive computing and networks. The challenge still is to adapt operations along all aspects of a sensing system (sensing, computation, communication), to deal with the varied, unpredictable or possibly intermittent supply of such energy. To understand these challenges, we currently lack sufficient tools to evaluate the impact of different energy harvesting and transfer models - which is further exacerbated due to the high cost of deploying such systems at a large scale. We present a generic, TOSSIM-based simulation framework to model energy harvesting and energy transfer, enabling rapid development of harvesting- and transfer-aware applications, protocols, and system software. Our evaluation shows that even an abstract simulation model can provide unique insights, such as frequent power outages and node reboots due to intermittent energy supply. Based on these insights, we further establish the utility of this framework by demonstrating how high level simulations can lead to a better choice of energy scheduling algorithms.
