In this paper, the authors investigate a cross-layer approach for Optical Multiple Input Multiple Output (O-MIMO) systems, using Mode Group Diversity Multiplexing (MGDM). More specifically, by adapting the selection criteria of the sub-optimal antenna used in MIMO radio systems, they propose a new strategy to improve the protocol performance in indoor optical networks. By using the Bell Laboratories lAyered Space-Time (BLAST) architecture (Physical layer) and the application of Go-Back-N (at link layer), they show a significant increase of the link throughput, compared with that of the capacity based algorithm. The simulation results show that the combination of transmitters according to the criterion of selection increases the total data rate of the system using Multi Mode Fibers (MMF).
