Summary:
Wireless sensor network (WSN) is a network of many smart devices or nodes which communicates wirelessly with each other. Sensor network was operate with small batteries which hard to replace and very expensive. Thus, cooperative MIMO techniques have been used in WSN to reduce the energy consumption in the sensor nodes to allow the battery save the energy constraint. There are three major techniques in cooperative MIMO such as beam forming, spatial multiplexing and space time code. In addition, MAC protocol which suitable with the cooperative MIMO transmission is required. Combination of MAC protocol and cooperative MIMO can achieve more energy efficient and lower latency for the sensor network.
