We study the problem of distributed scheduling in multi-hop MIMO networks. We first develop a ``MIMO-pipe" model that provides the upper layers a set of rates and SINR requirements, which capture the rate-reliability tradeoff in MIMO communications. The main thrust of this study is then dedicated to developing CSMA-based MIMO-pipe scheduling under the SINR model. We choose the SINR model over...
The traditional adaptive modulation and coding (AMC) scheme has been designed separately from higher protocol layers. In this paper, we consider the joint effects of finite-length buffer at the data link layer and the channel state information (CSI) at the physical layer for the adaptive transmission over the multiple input multiple output (MIMO) fading channel. A novel cross-layer adaptive transmission...
The physical layer of future wireless networks will be based on novel radio technologies such as UWB and MIMO. One of the important capabilities of such technologies is the ability to capture a few packets simultaneously. This capability has the potential to improve the performance of the MAC layer. However, we show that in networks with spatially distributed nodes, reusing backoff mechanisms originally...
