Previously, we have studied the throughput estimation model for the link in the IEEE 802.11n wireless local-area network (WLAN) in indoor and outdoor environments. In this model, 1) the received signal strength (RSS) at the receiving node is estimated by the log distance path loss model considering the distance and the obstacles along the link, 2) the throughput is obtained from the RSS by the sigmoid function, and 3) the parameters in these functions are optimized by the parameter optimization tool. This model has been evaluated for Single Input Single Output (SISO) links, although Multiple Input Multiple Output (MIMO) is common in IEEE 802.11n by increasing the transmission capacity and the reliability.
In this paper, we study the throughput estimation model for the IEEE 802.11n MIMO link. First, throughput measurements for MIMO links are conducted using commercial devices and software tools in three network fields. Then, using measurement results, the parameters in the model are optimized by our tool. For evaluations, estimated throughputs by the model are compared with measured ones and calculated ones by the ns-3 network simulator. The results show that our model can estimate throughputs with considerably high accuracy in any field. |
