Compressed Data Aggregation: Energy-Efficient and High-Fidelity Data Collection

  title={Compressed Data Aggregation: Energy-Efficient and High-Fidelity Data Collection},
  author={Liu Xiang and Jun Luo and Catherine Rosenberg},
  journal={IEEE/ACM Transactions on Networking},
We focus on wireless sensor networks (WSNs) that perform data collection with the objective of obtaining the whole dataset at the sink (as opposed to a function of the dataset). In this case, energy-efficient data collection requires the use of data aggregation. Whereas many data aggregation schemes have been investigated, they either compromise the fidelity of the recovered data or require complicated in-network compressions. In this paper, we propose a novel data aggregation scheme that… CONTINUE READING
