“…The problem of AP association in Wi-Fi networks has been broadly addressed in the state of the art. Among the most recent published papers on this topic, we can find works in [17] and [19], which are mentioned in the previous section, and works in [23]- [31]. Specifically, Saldana et al [23] presented a system managed by a central controller that gathers the capabilities of heterogeneous APs and users' stations (STAs) for efficient load balancing and mobility management.…”

“…However, the lack of consideration for satisfying users' requirements as a key input for AP association is a major limitation in many of these approaches [19], [23]- [26], [28]. The solutions proposed in [17], [27], and [29]- [31] address this limitation by presenting AP association solutions that consider the suitability of each traffic with a specific AP in terms of users' requirements.…”

“…[29]- [31] do not allow a reallocation of APs to Wi-Fi STAs that can experience different applications with corresponding different requirements while they are connected to the network, which might improve the performance. Furthermore, works in [17], [19] and [23]- [30] are not supported by a system that can guarantee trust and transparency among the cooperating stakeholders.…”

This paper proposes a novel trust-based cooperative system to facilitate efficient Wi-Fi network access trading to solve the network congestion problem in a beneficial manner for both service providers and customers. The proposed system enables service providers to improve their users' application performance through a novel cooperative Access Point (AP) association solution. The system is based on a Software-Defined Wireless Network (SDWN) controller, which has a global view of users' devices, requirements, and APs. The SDWN controller is supported by Smart Contracts (SCs) as code of law, to liaise control among service providers according to the terms of their mutual agreements. Evaluation results in dense Wi-Fi network environments show how the system can significantly improve the overall performance for the cooperating network. Specifically, the results have been compared against the standard AP association approach and other centralised algorithms dealing with the same problem, in terms of the data bit rate provided to the users' stations (STAs), Quality of Experience (QoE), bandwidth and energy consumed by the APs.

Aiming at the problems of low efficiency of buffer information collection and sharp drop of system throughput caused by the aggravation of conflicts in the multi basic service set (BSS) high density deployment overlap coverage scenario of next generation wireless local access network (WLAN), an access point cooperation based multi-BSS multi-user full duplex multiple access protocol named as CMMFD is proposed. Firstly, a channel resource allocation algorithm for stations (STA) in overlapping coverage area is designed, in which, the access control (AC) equipment allocates the channel resources for all STA in response to buffer state and interference information (BI) according to the proportion of STA in the overlapped coverage area. Secondly, a BI information collection protocol process based on access point (AP) cooperation sending trigger frame is designed to collect all STA information. After receiving trigger frame, STA will access the channel and report BI information in p-probability according to the channel resources allocated by AC. Finally, a multi-BSS multi-user channel resource allocation algorithm based on full duplex is designed. AC allocates channel resources according to all BI information reported by AP, and schedules STA in the multi-BSS to carry out multi-user full duplex transmission over the sub-channel. Simulation results show that the throughput of the CMMFD protocol improves by 29.6%, compared with Mu-FuPlex protocol and EnFD-OMAX protocol.
