Beacon Success Rate versus Gateway Density in Sub-GHz Sensor Networks.
Sensors (Basel)

Article Synopsis
- Multiple Gateways (GWs) enhance IoT sensor connectivity in a Wide Area Network (WAN) by facilitating diverse connections, but they also risk interference and collisions due to overlapping beacon transmissions.
- This study analyzes intra-network interference, proposing a new collision model that accounts for the Medium Access Control (MAC) and Physical (PHY) layers, focusing on the effects of collisions on packet loss rates.
- Performance evaluations suggest that increasing beacon intervals and using frequency hopping can minimize beacon loss rates, albeit with increased acquisition latency; meanwhile, higher GW densities can decrease discovery latency due to more available beacons.
