- Abstract
- A hybrid virtual multiple-input multiple-output (V-MIMO) transmission method of a management node in a wireless ad-hoc network in which a transmission path from a source node to a destination node is divided into one or more sections is provided. The hybrid V-MIMO transmission method includes obtaining one or more pieces of node information of one or more nodes by transmitting an information request message to the nodes in response to a transmission request message for data transmission from the source node to the destination node; setting a shortest path (SP) from the source node to the destination node based on the obtained node information; determining transmission schemes individually for nodes present on the SP; issuing a transmission preparation request by transmitting the determined transmission schemes to the respective corresponding nodes; and transmitting a transmission start message to the source node in response to transmission ready responses from the respective nodes.
