摘要：
Low-cost and low-power sensor nodes forming Wireless Sensor Networks (WSNs) have become suitable for a wide range of applications during recent years. These networks, due to their special functional characteristics, demand the implementation of energy-aware techniques in all layers. Recently a MIMO based structure has been proposed to offer enhanced energy savings in WSNs under certain circumstances. Based on that idea several alternatives have been examined, mainly focusing on 2x2 MEMO systems. In this paper, we summarize two MIMO schemes and compare their performance in terms of energy efficiency. Moreover, we investigate more complex NUM systems, emphasizing on 4x4 structures, and prove that depending on the scenario, such systems may offer remarkable energy gains.
