无线媒体本质上是广播的，因此容易受到干扰，因此需要高度优化的媒体访问控制（MAC）协议。这对于由大量小型化电池供电的无线网络传感器组成的无线传感器网络（wsn）来说尤其如此，这些传感器需要在没有人为干预的情况下运行多年。因此，近年来人们对理解和优化WSN MAC协议越来越感兴趣，在有限和受限的资源中，研究主要是为了降低MAC功能的能耗。在本文中，我们提供了一项全面的最新研究，其中我们彻底揭示了WSN MAC协议的主要焦点，启发这些协议的设计指南，以及现有解决方案的缺点和缺点，以及现有和新兴技术将如何影响未来的解决方案。以前的调查主要是根据所使用的技术对MAC协议进行分类，与此相反，我们提供了一个专题分类法，其中根据所处理的问题对协议进行分类。我们还表明，为特定情况选择合适的解决方案的关键因素主要是由生成流量的统计属性驱动的。
The wireless medium being inherently broadcast in nature and hence prone to interferences requires highly optimized medium access control (MAC) protocols. This holds particularly true for wireless sensor networks (WSNs) consisting of a large amount of miniaturized battery-powered wireless networked sensors required to operate for years with no human intervention. There has hence been a growing interest on understanding and optimizing WSN MAC protocols in recent years, where the limited and constrained resources have driven research towards primarily reducing energy consumption of MAC functionalities.In this paper, we provide a comprehensive state-of-the-art study in which we thoroughly expose the prime focus of WSN MAC protocols, design guidelines that inspired these protocols, as well as drawbacks and shortcomings of the existing solutions and how existing and emerging technology will influence future solutions.In contrast to previous surveys that focused on classifying MAC protocols according to the technique being used, we provide a thematic taxonomy in which protocols are classified according to the problems dealt with. We also show that a key element in selecting a suitable solution for a particular situation is mainly driven by the statistical properties of the generated traffic.
