This paper develops a Diversity-Multiplexing Tradeoff (DMT) over a bidirectional random relay set in a wireless network where the distribution of all nodes is a stationary Poisson point process. This is a nontrivial extension of the DMT because it requires consideration of the cooperation (or lack thereof) of relay nodes, the traffic pattern and the time allocation between the forward and reverse traffic directions. The authors then use this tradeoff to compare the DMTs of traditional Time-Division MultiHop (TDMH) and Network Coding (NC).
