Improving Massive Access to IoT Gateways

IoT networks handle incoming packets from large numbers of IoT Devices (IoTDs) to

IoT Gateways. This can lead to the IoT Massive Access Problem that causes bu er

overflow, large end-to-end delays and missed deadlines. This paper analyzes a novel

tra c shaping method named the Quasi-Deterministic Tra c Policy (QDTP) that mitigates

this problem by shaping the incoming tra c without increasing the end-to-end

delay or dropping packets. Using queueing theoretic techniques and extensive data

driven simulations with real IoT datasets, the value of QDTP is shown as a means

to considerably reduce congestion at the Gateway, and significantly improve the IoT

network’s overall performance.
