This paper presents a virtual multiple-input and multiple-output (MIMO) configuration (abbreviated VMC) approach for massive data transmission in the Internet of Things (IoT), which coordinates distributed gateways (GWs) with a single antenna to implement MIMO capability virtually. The operation of the VMC consists of two steps: 1) multiple distributed GWs (dGWs) logically construct one virtual gateway (vGW) which behaves like a GW equipped with multiple antennas, and 2) using the constructed vGW, the VMC conducts the traffic scheduling and thereby enables virtual MIMO. Through simulation, we verified that the VMC achieves a higher network throughput than the legacy network by at least 16%. Moreover, we evaluated the variations in channel access time of the VMC under various network conditions.
