Outline of Final Research Achievements

This research investigates the radio channel access technique for the group-based medium access control (GMAC) with restrict access window (RAW) in IoT/M2M wireless networks with massive user stations (STAs). Focusing on traffic non-uniformity, this research proposes the STA grouping strategy for RAW based GMAC access in IoT/M2M wireless networks, which handles various traffic non-uniformities such as non-uniform STA deployment, STA traffic, and STA data rate.
This research demonstrates the proposed STA grouping strategy improves the system performance, such as system throughput and fairness in communication between STAs.
