Maximizing the data utility of a data archiving & querying system through joint coding and scheduling
Junning Liu, Zhen Liu, Don Towsley, Cathy Honghui Xia · 2007
We study a joint scheduling and coding problem for collecting multi-snapshots spatial data in a resource constrained sensor network. Motivated by a distributed coding scheme for single snapshot data collection [7], we generalize the scenario to include multi-snapshots and general coding schemes. Associating a utility function with the recovered data, we aim to maximize the expected utility gain through joint coding and scheduling.
