Collaborative relays achieve the benefits of spatial diversity without requiring any physical antenna arrays at wireless devices. While many studies have demonstrated its effectiveness in a single source-destination system, applying cooperative relays to large-scale wireless networks remains challenging. We show that a system with cooperative relays can be penalized by the extra level of interference it produces. By examining the inter-dependency between interference management and cooperative relay strategies, we model the penalty by an increase in spectrum resource usage, and translate it into a penalty of single-link performance. This penalty serves as a reference for cooperative relay design in a single-link scenario. We then present two practical spectrum allocation mechanisms for collaborative relay systems with different fairness and utilization tradeoffs. Simulation results confirm our analytically findings.
