Small-size and light-weight, as the modern design concept for the emerging wearable devices, has become a trend. However, such trend puts physical limitations to the battery, and the resulting short battery lifetime becomes the bottleneck for most wearable devices today. In this paper, we aim to optimize the energy usage through data compression and transmission rate control. We propose a novel joint...
Data deduplication can reduce cost and enhance throughput in backup and archiving systems. Recently, it becomes increasingly popular to apply this technique in primary storage systems, where data is actively used by enterprise business applications. However, the state-of-the-art deduplication systems for primary storages mainly provide offline solutions, which require sufficient time-window, additional...
Energy management stands out as a crucial design and operational factor for the emerging wearable devices. In this paper, we investigate how to reduce the data-transmission energy for multi-sensor wearable devices over stochastic wireless channels. Specifically, we formulate the data-transmission scheduling issue into a constrained optimization problem, with an objective to minimize the time-average...
