Energy efficient data transfer is one of the key factors for Wireless Sensor Network (WSN). Cooperative MIMO explores the wireless communication schemes between multiple sensors emphasizing the Multiple Input Multiple Output (MIMO) structure. An energy efficient cooperative technique is proposed for a WSN where selected numbers of sensors at the transmitting end are used to form a MIMO structure wirelessly connected with selected number of sensors at the receiving end. The selection of nodes in the transmitting end is based on a selection function which is a combination of channel condition, residual energy, inter sensor distance in a cluster and geographical location whereas the selection in receiving side is performed on the basis of channel condition.
