Abstract(in English) | In this paper, we propose apply to MU-MIMO (Multi-User Multiple-Input Multiple-Output) to wireless mesh networks. If the number of the packets whose receiver node is the same is not enough large, SU-MIMO (Sinle-User MIMO) cannot achieve capacity enhancement by the spatial multiplexing. By contrast, the efficiency of MU-MIMO will be always high because it can simultaneously transmit packets to multiple neighbor nodes. A hidden node problem is, however, a difficult issue in wireless mesh networks and causes the performance degradation. In this study, the performances of SU-MIMO and MU-MIMO in wireless mesh networks are analyzed and compared. Prom a result, MU-MIMO is superior to SU-MIMO if queue size of each node is not sufficiently large by comparison with the number of neighbor nodes. It is also shown that the influence of collisions is identical between MU-MIMO and SU-MIMO. |
