PC/workstation DBMS provide a set of data management functions in a stand-alone fashion as a single-user system on a personal computer or workstation. There is no real data exchange between a PC/workstation DBMS and other data management systems, remote users, or DBMS at another place. Some PC/workstation DBMS provide limited functions to extract data as a "snapshot" from a remote database to p...

Recently, over-the-air computation (AirComp) has emerged as an efficient solution for access points (APs) to aggregate distributed data from many edge devices (e.g., sensors) by exploiting the waveform superposition property of multiple (uplink) channels. While prior work focuses on single-cell setting where inter-cell interference is absent, this article considers a multi-cell AirComp network ...
