Speech Title: Stable and Fresh Massive Access for Passive IoT
Abstract: Battery-free sensors that can be energized wirelessly are promising for continuously sensing the physical world and providing time-sensitive data for intelligent decisions and applications. The deployment of such ambient power-enabled IoT usually involves massive access of the passive sensors. This talk would introduce how to control access of the massive sensors so that the systems are stable and the collected data is fresh from MAC layer perspective. Specifically, this talk focuses on random access named Frame Slotted Aloha (FSA) with its stability and age of information (AOI) presented in sequence. These theoretical results could provide guidelines for stable and fresh FSA-based access protocol design.
