The authors address the problem of exchanging broadcast packets from multiple wireless terminals through a single relay node. The objective is to evaluate the delay and throughput gains of network coding over plain routing. They compare digital network coding at the packet level with analog network coding based on scheduled or random access of terminal transmissions that are forwarded by the relay node. For error-free channels, the performance gain of network coding scales with the number of terminals, if they can overhear each other's transmissions. For channels with noise or packet erasures, they formulate network coding as a multiuser communication problem.
