In this paper, the authors study the problem of determining the minimum scheduling length that can satisfy End-To-End (ETE) traffic demand in scheduling-based multi-hop WSNs with cooperative Multiple-Input Multiple-Output (MIMO) transmission scheme. Specifically, they present a cross-layer formulation for the joint routing, scheduling and stream control problem by incorporating various power and rate adaptation schemes, and taking into account an antenna beam pattern model and the Signal-to-Interference-and-Noise (SINR) constraint at the receiver. In the context, they also propose Column Generation (CG) solutions to get rid of the complexity requiring the enumeration of all possible sets of scheduling links.
