This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Many sensor network deployments are in harsh terrain that lack infrastructure but also need to use solar energy harvesting for self-sustained operation. The design of harvesting-aware solar sensor networks raises numerous systems and networking challenges. From a systems perspective, a design should be able to operate under a wide dynamic range of energy harvesting scenarios, from plentiful sunlight to very limited light (e.g., thickly forested areas). From a network perspective, a protocol stack should be able to adapt to spatio-temporal variability in harvesting rates due to foliage and day-to-day vagaries.In this project, we will design systems and network support for harvesting-aware solar sensor networks. Our systems contributions include novel sensor platforms that use thin-film batteries for harvesting under low-light conditions, predictive duty-cycling under highly variable harvesting conditions, and lightweight checkpointing and restart to handle intermittent loss of power. Our networking contributions include a link layer that is optimized for duty-cycle variability, a network layer that uses harvesting-aware path metrics, and a transport layer can offer high throughput under diverse harvesting conditions.Our educational plans consist of K-12 teaching through a summer high school outreach program, and inter-disciplinary REU programs in collaboration with Harvard Forest for deploying solar-powered sensor networks for ecological monitoring.

该奖项是根据2009年的《美国回收与再投资法》（公共法第111-5号）资助的。许多传感器网络部署处于缺乏基础设施的严酷地形，但也需要使用太阳能收集进行自我维持的操作。 收获感知太阳能传感器网络的设计增加了许多系统和网络挑战。 从系统的角度来看，设计应该能够在能量收集的各种动态范围内进行操作，从丰富的阳光到非常有限的光线（例如，茂密的森林地区）。 从网络的角度来看，协议堆栈应该能够适应由于叶子和日常变异而引起的收获率时期的时空变异性。在这个项目中，我们将设计系统和网络支持，用于收获感知的太阳能传感器网络。 我们的系统贡献包括使用薄膜电池在低光条件下收获的新型传感器平台，在高度可变的收获条件下进行预测税收循环以及轻巧的检查点和重新启动以处理间歇性损失的权力损失。 我们的网络贡献包括一个针对税收周期可变性进行优化的链路层，使用收获感知路径指标的网络层，运输层可以在各种收获条件下提供高通量。我们的教育计划包括通过夏季高中课程的K-12教学，与Harvard Forest在Harvard Forest合作进行待办Solaring Sensor网络，由夏季高中的外展计划，与您的跨学科REU计划一起工作，以供您供应服务。
