The authors of "Powering the Next Billion Devices with Wi-Fi" turn the problem of powering wireless sensor networks on its head. Instead of focusing on energy harvesting, they focus on wireless energy transfer.
We present the first power over Wi-Fi system that delivers power to low-power sensors and devices and works with existing Wi-Fi chipsets.
What is the most drastic way to reduce the cost of communication for parallel data processing algorithms? This is the question studied in "Reasoning on Data Partitioning for Single-Round Multi-Join Evaluation in Massively Parallel…
We introduce a framework for reasoning about data partitioning to detect when we can avoid the data reshuffling step.
