Software-defined wireless sensor networks (WSNs) are a new and emerging network paradigm that seeks to address the impending issues in WSNs. It is formed by applying software-defined networking to WSNs whose basic tenet is the centralization of control intelligence of the network. The centralization of the controller rouses many challenges such as security, reliability, scalability, and performance. A distributed control system is proposed in this paper to address issues arising from and pertaining to the centralized controller. Fragmentation is proposed as a method of distribution, which entails a two-level control structure consisting of local controllers closer to the infrastructure elements and a global controller, which has a global view of the entire network. A distributed controller system brings several advantages and the experiments carried out show that it performs better than a central controller. Furthermore, the results also show that fragmentation improves the performance and thus have a potential to have major impact in the Internet of things.

软件定义无线传感器网络的基于分段的分布式控制系统


软件定义的无线传感器网络 (WSN) 是一种新兴的网络范例，旨在解决 WSN 中迫在眉睫的问题。它是将软件定义网络应用于无线传感器网络而形成的，其基本宗旨是网络控制智能的集中化。控制器的集中化带来了安全性、可靠性、可扩展性、性能等诸多挑战。本文提出了一种分布式控制系统来解决集中控制器引起的和与之相关的问题。分段被提出作为一种分布方法，它需要一个两级控制结构，由更靠近基础设施元素的本地控制器和具有整个网络全局视图的全局控制器组成。分布式控制器系统具有多种优点，并且进行的实验表明它比中央控制器性能更好。此外，结果还表明，碎片化可以提高性能，从而有可能对物联网产生重大影响。
