12	Average Throughput Performance
13	Average Throughput Performance
14	Improving Average Case Performance “Optimal Codes” for highest minimum throughput guarantees often have many more codewords than number of nodes in the network Idea: carefully select subset of codewords that are actually used (previous analysis assumes all codewords are equally likely to be used) The proposed code-selection procedure chooses code-words that have mutual maximum-average Hamming distance.
15	Codeword Selection: Results
16	Conclusion and future work
