Network Coding for the Multiple Access Layer
Danail Traskov · 2010
In this work, we address network coding for the multiple access layer in wireless networks. We propose a scheduling technique that activates hyperarcs rather than arcs, as in classical link-based scheduling, and therefore can harness the gains of random network coding. We show that jointly optimizing the network coding subgraph and the transmission schedule leads to a substantial performance improvement. We also look at relaxing the assumption of synchronization in the network and extending network coding to take place across different independent sessions. Finally, we address the relationship between throughput and delay for network coded transmissions in erasure broadcast channels.
