Network Coding for Undirected Information Exchange
Jasper Goseling, Christina Fragouli, Suhas N. Diggavi · IEEE Communications Letters · 2009
We consider the information exchange problem where each in a set of terminals transmits information to all other terminals in the set, over an undirected network. We show that the design of only a single network code for multicasting is sufficient to achieve an arbitrary point in the achievable rate region. We also provide an alternative proof for the set of achievable rate tuples.
