Abstract

In recent years, wireless LANs (WiFi) has been a popular options for mobile devices to connect to the network. As networks are becoming larger and more complex, solutions that simplify network operation and management are urgently needed. Software Defined Networking (SDN) is a state-of-the-art paradigm addressing this issue. While SDN is basically very general, in this work, networking performance related to the handover events is addressed in SDN-based wireless networks. For the investigation, Mininet WiFi, an extension to Mininet as the most popular SDN emulation environment, is used. Two association methods supported in Mininet Wi-Fi are Strongest-Signal-First (SSF) and Least-Loaded-First (LLF). These two methods has their own mechanisms. In this research, an experiment is conducted to observe how association control works in handover scenario. A performace analysis of transfer, jitter, and packet loss are also discussed. The result of the experiment is LLF gains better performance than SSF mode in every sub-scenario.

基于sdn的无线网络中切换关联机制的性能评价

近年来，无线局域网(WiFi)已经成为移动设备连接网络的一种流行选择。随着网络的日益庞大和复杂，迫切需要简化网络操作和管理的解决方案。软件定义网络(SDN)是解决这个问题的最先进的范例。虽然SDN基本上是非常通用的，但在这项工作中，与切换事件相关的网络性能是在基于SDN的无线网络中解决的。为了进行调查，使用了Mininet WiFi，这是最流行的SDN仿真环境Mininet的扩展。Mininet Wi-Fi支持的两种关联方法是最强信号优先(SSF)和最小负载优先(LLF)。这两种方法都有各自的机制。在本研究中，通过实验来观察关联控制在切换场景下的工作原理。还讨论了传输、抖动和丢包的性能分析。实验结果表明，在每个子场景下，LLF模式的性能都优于SSF模式。
