The authors design a cross-layer approach to aid in developing a cooperative solution using Multi-Packet Reception (MPR), Network Coding (NC), and Medium ACcess (MAC). They construct a model for the behavior of the IEEE 802.11 MAC protocol and apply it to key small canonical topology components and their larger counterparts. The results obtained from this model match the available experimental results with fidelity. Using this model, they show that fairness allocation by the 802.11 MAC can significantly impede performance; hence, they devise a new MAC that not only substantially improves throughput, but provides fairness to flows of information rather than to nodes.
