【摘要】：信息时代的众多网络应用需求孕育了多种多样的无线网络通信协议,蓬勃发展的物联网将众多无线网络协议纳入了一个共同的网络框架内.随着物联网系统的广泛应用,同一区域内,尤其在室内环境中,多种无线网络协议共存的情况越来越普遍.众多共存的无线网络协议不仅不能彼此分享数据信息,反而会对彼此造成干扰,影响通信效率.因此,无线网络协议共存技术近年来成为了工业界和学术界的研究热点.然而现在关于2.4GHz频段上的无线网络共存的综述研究或仅仅针对某2种协议间的共存,或缺少对最新技术的总结.因此,在重新梳理相关研究的基础上,介绍了共存问题的成因,分析了共存问题的影响,按照共存环境复杂性,回顾了现有工作提出的关键共存技术,包括同质干扰的避让、容忍和并发传输,异质干扰的检测、识别和异质干扰环境下的共存传输.最后,展望了物联网发展大环境下共存技术的发展趋势——更广泛的互联互通.
[Abstract]:Many network applications in the information age breed a variety of wireless network communication protocols. The booming Internet of things brings many wireless network protocols into a common network framework. With the wide application of the Internet of things system, the same area, especially in the indoor environment. The coexistence of multiple wireless network protocols is becoming more and more common. Many wireless network protocols not only can not share data information with each other, but will interfere with each other and affect the communication efficiency. In recent years, wireless network protocol coexistence technology has become a hot topic in industry and academic circles. However, the research on the coexistence of wireless networks at 2.4 GHz band has been reviewed or only aimed at the coexistence of two kinds of protocols. . Or the lack of summary of the latest technology. Therefore, on the basis of re-combing the relevant research, introduced the causes of coexistence problems, analyzed the impact of coexistence problems, according to the complexity of coexistence environment. This paper reviews the key co-existing technologies, including the avoidance of homogeneous interference, tolerance and concurrent transmission, heterogeneous interference detection, recognition and coexistence transmission in heterogeneous interference environment. The development trend of coexistence technology in the environment of Internet of things development is prospected-more extensive interconnection and interworking.
