摘 要:随无线传感器网络的广泛应用,网络传输协议设计也多种多样。但是,延长传感器网络的寿命,即寻找具有能效的设计一直是非常重要的问题。因为多输入多输出(MIMO)技术具有增加网络容量,减少衰落信道中能量消耗的能力,所以虚拟MIMO技术已经成为无线传感器网络中有效的节能解决方案之一。以三个典型的协议为例来介绍虚拟MIMO与无线传感器网络相结合的协议设计,并且讨论设计中的关键技术与注意事项,最后提出该项技术未来的研究方向。As wireless sensor networks (WSN) are used more widely, the design of network transmission protocol will be largely various. However, prolonging WSN' s lifetime, namely, searching an energy-efficient protocol design, becomes a very important issue. As multiple-input multiple-output (MIMO) technique has the potential to dramatically increase the channel capacity or reduce transmission energy consumption in fading channel, virtual MIMO technique has been one of the effective solutions to minimize the energy consumption in WSN. Three typical WSN protocols are presented as examples of protocol designed with virtual MIMO technique in WSN, and discussed the crucial problems and some considerations in the design, together with suggestion for future applications and researches.
