Abstract:
In this paper, we investigate the performance issue of massive Internet of Things (IoT) by evaluating to what extent the number of devices can be accommodated. We build a system level simulator based on the 3GPP TR 45.820 Narrow-Band IoT standard. We find that the current First In First Out (FIFO) approach can serve 630 devices per base station assuming that one device can be served at a time. Then, we develop the scheduling techniques - maximal delay tolerance and alpha-maximum tolerance for a system-level performance analysis. Our experiment results show that the proposed scheduling techniques outperform at least 2.8 times compared with the FIFO policy.
