Distributed CSMA Algorithms for Link Scheduling in Multi-Hop MIMO Networks Under SINR Model
In this paper, the authors study 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 that capture the rate-reliability tradeoff in MIMO communications. The main thrust of this study is then dedicated to developing distributed CSMA algorithms for MIMO-pipe scheduling under the SINR interference model. They choose the SINR model over the extensively studied 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 under the SINR model makes the problem of devising distributed scheduling algorithms very challenging.
