Minimizing Age of Information in Nonorthogonal Random Access Networks

In this article, we aim to minimize the Age of Information (AoI) for a random access Internet of Things (IoT) network, where AoI is a metric to measure the freshness of information delivery. Since nonorthogonal multiple access (NOMA) can improve network throughput and connectivity, we exploit an AoI...
