A method similar to the CMIMO is adopted to carrying out clustering on a network for the GCMIMO, and each cluster is managed by two cluster heads, namely a main cluster head and a secondary cluster head. The main cluster heads are used for dividing information source nodes in the corresponding clusters into a plurality of cooperative groups, each cooperative group is composed of two adjacent information nodes, is equivalent to a virtual double-antenna sending end and is used for sending information source data of the cooperative groups, the secondary cluster heads and the main cluster heads are considered as one cooperation group which is called as a main cooperative group and used for receiving and forwarding the data of other cooperative groups, and therefore multi-hop virtual MIMO transmission is achieved. Different from an existing virtual MIMO communication strategy, the GCMIMO does not need to collect information source data through the cluster heads and directly sends the information source data through the cooperative groups, so that the forwarding frequency of the information source data is reduced and the energy efficiency of intra-cluster communication stages is improved. In a simulation experiment, energy consumption analysis of each communication stage of the GCMIMO proves that the GCMIMO effectively lowers the energy consumption of intra-cluster communication and network maintenance frequency, and improves energy efficiency.
