As users all know, virtual MIMO (Multiple-Input and Multiple-Output) technology is an efficient way for energy saving in Wireless Sensor Networks (WSNs). The present virtual MIMO communication strategies in WSNs depend on cluster heads collecting and forwarding source data, which cause big energy consumption. Aiming at this problem, the authors propose a new virtual-MIMO communication strategy based on Cooperative Group (CG) in this paper, called Group Collaboration MIMO (GCMIMO). GCMIMO clusters the WSN into several clusters. Each cluster is managed by two cluster heads, Master Cluster Head (MCH) and Vice Cluster Head (VCH).
