This paper investigates the benefits of cooperation in large wireless networks with multiple sources and relays, where the nodes form an homogeneous Poisson point process. The source nodes may dispose of their nearest neighbor from the set of inactive nodes as their relay. Although cooperation can potentially lead to significant improvements on the asymptotic error probability of a communication pair, relaying causes additional interference in the network, increasing the average noise. The authors address the basic question: how should source nodes optimally balance cooperation vs. interference to guarantee reliability in all communication pairs.
