Dynamic Switching Access in Massive Machine Type Communication

The widespread use of Machine Type Communication (MTC) has sparked a surge in Machine to Machine traffic, creating a need for efficient wireless network management strategies. The conventional Random Access approach struggles to accommodate the substantial influx of devices that characterize MTC deployment, leading to congestion, delays, and resource wastage. To address these challenges, this study introduces Dynamic Switching Access (DSA), a novel multiple access technique that intelligently alternates between Grant Free and Grant Based protocols based on device intensity. By dynamically adjusting thresholds, DSA capitalizes on the strengths of both protocols, effectively enhancing overall system performance even in scenarios with fluctuating traffic loads. Simulation results conclusively demonstrate that the proposed DSA approach outperforms individual protocols in various multiple access scenarios.
