Executive Summary

The authors study the problem of distributed scheduling in multi-hop MIMO networks. They first develop a "MIMO-pipe" model that provides the upper layers a set of rates and SINR requirements, which capture the rate-reliability trade-off in MIMO communications. The main thrust of this paper is then dedicated to developing CSMA-based MIMO-pipe scheduling under the SINR model. They choose the SINR model over the extensively studied matching or protocol-based interference models because it more naturally captures the impact of interference in wireless networks. The coupling among the links caused by the interference makes the problem of devising distributed scheduling algorithms particularly challenging. To that end, they explore CSMA-based MIMO-pipe scheduling, from two perspectives.
