Performance Analysis of an Adaptive Queue-Aware Random Access Scheme with Random Traffic

In this work, we consider an adaptive two-user random access scheme with multipacket reception (MPR) ca- pabilities. A user adapts its transmission characteristics based on the status of the other user. The users have external random traffic stored in their queues. We derive the stable throughput region of the system and the convexity conditions of this region. We derive analytically the queueing delay by formulating and solving a Riemann-Hilbert boundary value problem. Finally, we evaluate numerically the presented theoretical results. CENIITEU project DECADE under Grant H2020-MSCA-2014-RISE: 64570
