The rapid advances of MIMO to date have mainly stayed at the physical layer. Such fruits have not been fully benefited at the network layer mainly due to the computational complexity associated with the matrix-based model that MIMO involves. Recently, there are some efforts to simplify link layer model for MIMO so as to ease research for the upper layers. These models only require numeric computations on MIMO's Degrees-of-Freedom (DoFs) for Spatial Multiplexing (SM) and Interference Cancellation (IC) to obtain a feasible rate region.
