【摘要】：近年来,嵌入式技术与无线网络技术深度结合,催生了可计算RFID、嵌入式传感网等新兴领域.这些系统由大量廉价的节点组成,应用前景广泛.在传统设计中,这些系统通常是根据应用定制的.根据应用定制的系统具有开发简便、运行高效等优点,但不适合未来大规模部署.这是因为如果这些系统跟应用密切绑定、难以更新,那么系统一经部署就难以更新其软件,从而阻碍了软件创新的进程.软件定义的思想可以有效解决该问题.当前,软件定义网络成为计算机网络中一个热门的研究领域.传感器网络的软件设计与因特网的软件设计存在诸多差异,其最大的差异在于,传感器网络主要以信息的采集为核心,而因特网主要以信息的传输为核心.此外,传感器节点还具有体积小、电池续航能力有限、价格低廉等特点.文中主要调研了设计软件定义传感器网络(Software-Defined Sensor Networks,SDSNs)架构的相关工作,列举了在设计一个通用、高效的软件定义传感器网络架构时可能遇到的挑战,并回顾了一些有用的技术.这些技术有的来自于现有方案,有的能够直接被用来解决一部分挑战.此外,文中还从软件定义功能的角度,进一步地对目前通用、高效的软件定义传感器网络架构及其采用的技术进行了分类.我们认为,软件定义传感器网络架构将在已部署的网络中起到至关重要的作用,并带来一场新的技术变革.
[Abstract]:In recent years, embedded technology and wireless network technology have been deeply combined, giving birth to computing RFID, embedded sensor network and other emerging fields. These systems are composed of a large number of cheap nodes and have a wide application prospect. In traditional design, these systems are usually customized according to the application. The system customized according to application has the advantages of simple development and efficient operation, but it is not suitable for large-scale deployment in the future. This is because if these systems are closely bound to the application and difficult to update, then the system once deployed is difficult to update its software, thus hindering the process of software innovation. The idea of software definition can solve this problem effectively. At present, software defined network has become a hot research field in computer network. There are many differences between the software design of sensor network and the software design of Internet. The biggest difference lies in that sensor network mainly takes the collection of information as the core, and the Internet mainly takes the transmission of information as the core. In addition, the sensor node has the characteristics of small size, limited battery capacity and low price. This paper mainly investigates the related work of designing Software-Defined Sensor Networks (Software defined Sensor Networks) architecture, lists the possible challenges in designing a general and efficient software architecture for WSN, and reviews some useful techniques. Some of these technologies come from existing solutions, and others can be used directly to address some of the challenges. In addition, from the point of view of software definition function, this paper further classifies the current general and efficient software-defined sensor network architecture and its adopted technology. We believe that software definition of sensor network architecture will play a vital role in deployed networks and bring about a new technological change.
