“…This architecture standardizes communications between APs and a WLAN controller, by providing a uniform interface for performing control and management operations such as initial procedures for controller discovery, updating firmware images, and monitoring and the configuration of the AP behavior. However, schemes that are only based on this approach (e.g., [31][32][33]) raise serious concerns about flexibility, mainly owing to the inability of CAPWAP to provide network programming capabilities [34].…”

Ultradense Networks (UDNs) seek to scale the 5th-Generation mobile network systems at unforeseen amounts of networks, users, and mobile traffic. We believe that the Wi-Fi sharing service is an asset in expanding 5G UDN capacity requirements for higher coverage and ubiquitous wireless broadband connectivity. However, the limitations of the Wi-Fi sharing pioneer deployment, along with other related works, has led our team to carry out further research. As a result, it was found that FOg CloUd Slicing for Wi-Fi sharing (FOCUS) is a suitable means of expanding 5G UDN capacities. FOCUS applies end-to-end Network-Cloud slice definitions on top of the Wi-Fi sharing technology, with the aim of offering multitenancy and multiservice support for a wide range of services, while meeting carrier-grade requirements and resource control at runtime and making full use of a “softwarized” approach. The feasibility of the FOCUS system is assessed in a real testbed deployment prototype, which allows an accurate view to be obtained of the basic functional principles and system-level proof-of-concept alongside the FON de facto Wi-Fi sharing service. The results suggest that FOCUS offers much greater benefits than FON, owing to its capacity to provide end-to-end Network-Cloud Slices while ensuring independent/isolated service delivery with resource adaptation at runtime.

“…Mobility management in enterprise WLANs is of two types: mobile device driven or distributed [1,2] and network driven or centralized [3,4]. In [5] and [6], details are provided about other related works on mobility management in enterprise WLANs. We do not present additional details about these works here.…”

“…This design provides a global view of the entire WLAN at the logically central SDN Controller. The NATbased handover mechanism [5] has been proposed using the SDN-based enterprise WLAN framework proposed in [6]. The handover mechanism periodically checks if any mobile device is moving away from its connected AP and, if so, then it initiates handover for all those roaming mobile devices.…”

Many modern-day applications require seamless connectivity to provide a good quality experience to mobile users. Thus, mobility management mechanism becomes a crucial aspect of all the wireless technologies used to connect to the Internet. In this letter, we present the testbed implementation details of a Network Address Translation (NAT)-based, client-unaware, seamless handover mechanism for a Software-Defined Enterprise WLAN framework. The results from the testbed implementation corroborate that the handover mechanism can provide uninterrupted connectivity during a handover process.

To satisfy the need for ubiquitous connectivity of their customers, many enterprises (e.g., hotels, cafes and commercial centers) deploy EWLAN (Enterprise WLAN). In these networks, video streaming is both one of the most popular and challenging applications. To improve the overall users QoE in EWLAN, we propose to address simultaneously the resource bottlenecks that can occur on wireless links as well as the lack of overall bandwidth that can be experienced on the Internet access link. We propose a dynamic video Streaming Management based on software defined enterprIse wireLEss LANs (SMILE), an SDN framework which dynamically allocates the bandwidth among different access points based on their workloads and on the available bandwidth. We evaluate SMILE over several adaptive video streaming performance metrics: instability, rebuffering, and average video quality. The results demonstrate an improvement for these parameters with different adaptation logic's when SMILE is in use.
