Abstract

We propose a user-scheduling scheme for uplink opportunistic nonorthogonal random access in a finite blocklength Internet-of-Things (IoT) network. The considered system consists of high-priority IoT (HP-IoT) devices requiring strict quality-of-service (QoS) and low-priority IoT (LP-IoT) devices with delay-tolerance. Active LP-IoT devices opportunistically transmit their data subject to the QoS constraints of the HP-IoTs. We first analyze the sum-throughput achieved by the LP-IoT devices. Next, we devise greedy algorithm and Kuhn-Munkres algorithm-based schemes for user scheduling to maximize the throughput. Numerical results are provided to demonstrate the effectiveness of our proposed scheme over the conventional approach.
