%0 Journal Article %T On the Stability Region of a Relay-Assisted Multiple Access Scheme %A Nikolaos Pappas %A Marios Kountouris %A Anthony Ephremides %A Apostolos Traganitis %J Computer Science %D 2013 %I arXiv %X In this paper we study the impact of a relay node in a two-user network. We assume a random access collision channel model with erasures. In particular we obtain an inner and an outer bound for the stability region. %U http://arxiv.org/abs/1309.1338v1
