Status update strategies for wireless sensing applications

A major revolution of the next-generation wireless technologies is envisioned to enable internet of senses to turn the network infrastructure as a platform to deliver digitized sense of experiences. Numerous sectors such as smart city, industry 4.0, vehicular to everything (V2X), and remote healthcare, will be upgraded to support intelligent interactions with environment through internet of senses. To this end, a large set of data, representing the current status of the target, need to be measured by various kinds of sensors and wearables and then delivered timely to the monitor, which interprets and predicts the status changes of the target, using artificial intelligence (AI).

The status sensing process and the status update policy are two key components in a status updat network. Existing work on status update policy design commonly assumes ideal channel conditions with eligible transmission errors and the transmission resources in terms of bandwidth and power are nearly unconstrained. For wireless status networks, the error-prone fading channels and scarce radio resources require careful design of the status update policy. In this work, we will address the status update problem for efficient and reliable status update over wireless channels.
