Software Defined Network for Qos Enhancement in Mobile Wi-Fi Network
Wi-FI has become one of the dominant technology for direct access to the Internet due to its expanded services offering, its simplicity and its high-bandwidth provisioning that gives a capacity to support high traffic. Software-defined network (SDN) architecture simplified network management through an automatically programmed network. It provides a separation between the control plan (Controller) and the data plan (Switch) functions of the networks, this allows network optimization and fast response to network changes without the need to manually reconfigure existing infrastructure or purchase new hardware. In this paper, we have proceeded by studying the exchanges during a mobility within a WI-FI-based SDN network, then a network performance evaluation has been performed in order to analyze the impact of introducing the SDN concept on the performance of a mobile Wi-Fi network. For all proposed scenarios, we notice that the Wi-Fi-Based SDN architecture gives better results than in the case of the traditional Wi-Fi network.
