To solve this problem, a synergy between Software-Defined Networking (SDN) and WSN has been proposed. This paper aims to present the current status of Software-Defined Wireless Sensor Network (SDWSN) proposals and introduce the readers to the emerging research topic that combines Machine Learning (ML) and SDWSN concepts, also called ML-SDWSNs.

软件定义网络 (software-defined networking, 简称SDN)是一种全新的网络体系框架, 已被视为未来网络的重要样式之一 [10].网络抽象将控制面从数据面中解耦出来, 数据面仅负责路由转发, 控制面则实现路由决策, 而应用面为用户提供网络可编程服务, 从而极大增强了网络的灵活性.OpenFlow是SDN网络体系框架中的南向接口协议, 负责提供一系列规范, 以实现网络数据流的通用转发和高效操纵 [11].目前, OpenFlow是应用SDN技术的主流, 在一定程度上推动了SDN的发展.清华大学张 …

Software-defined WSNs (SDWSNs) offer a solution by enabling centralized control of low-power WSNs. However, continuously updating the controller with the network state generates significant traffic, resulting in energy loss, increased overhead, and reduced scalability and network lifetime.

2023年6月1日 · Software-Defined Networks (SDN), a trending networking technology, offers promising solutions to address the inherent problems of wireless networks, particularly Wireless Sensor Networks (WSN). The integration of SDN into WSN ushers in a new networking paradigm known as Software-Defined Wireless Sensor Network (SDWSN).

2017年2月8日 · SDN decouples the control plane from the data plane, thus moving the control logic from the node to a central controller. A wireless sensor network (WSN) is a great platform for low-rate wireless personal area networks with little resources and short communication ranges.

2018年7月5日 · In this paper, we propose an Energy-efficient Trust Management and Routing Mechanism (ETMRM) for SDWSNs to handle the malicious forwarding attacks, such as selective forwarding attack and new-flow attack.

2018年9月29日 · Wireless Sensor Networks (WSNs) play a greater role in short range communication networks. Their application adoption to mission critical systems has increased...

2024年2月5日 · 本研究提出了一个可扩展的 SDWSN 框架（SSDWSN）来应对这些挑战。 所提出的方法侧重于调度、平衡路由、聚合以及减少由控制器的定期网络状态更新引起的流量开销。 本文介绍了所提出框架的架构以及深度强化学习（DRL）代理。 它还提出了两种基于近端策略优化（PPO）的学习策略，即PPO-ATCP和PPO-NSFP。 这些策略旨在有效利用 SDWSN 网络资源，并通过持续监控控制器内的同步网络状态、采取适当的行动并根据奖励函数更新学习参数来 …
