Status Update for Accurate Remote Estimation: Centralized and Decentralized Schemes
IEICE transactions on communications
In this work, we consider a remote estimation system where a remote controller estimates the status of heterogeneous sensing devices with the information delivered over wireless channels. Status of heterogeneous devices changes at different speeds. With limited wireless resources, estimating as accurately as possible requires careful design of status update schemes. Status update schemes can be divided into two classes: centralized and decentralized. In centralized schemes, a central schedulerdoi:10.1587/transcom.2021cei0002 fatcat:hzoxut23ybevtglepp6q42j4eq
