“…But the paper [10] did not consider how T XOP can effect the performance of the network. In [11], the authors introduced an advancement of EDCA scheme for dense IEEE 802.11 ax schemes. The authors extended the EDCA queues from 4 to 7 to assign the priority levels to different kinds of video traffic (HD, 4K/8K videos), but the paper did not consider the impact of tuning the network parameters.…”

Globally, there is a significant rise in the number of connected devices. Every device has an access to wide variety of telecom services among which voice, video and best effort (BE) contribute significantly. There is a noticeable growing trend towards upstream BE traffic besides real time e-services that demand high quality of service (QoS). Converged next-generation fiber-wireless (FiWi) access networks composed of next-generation passive optical network (XG-PON) and 802.11n based wireless local area network (WLAN) has emerged as a suitable choice to provide high quality and affordable e-services to plenty of subscribers as they possess both high bandwidth and flexibility. In this paper, we study the performance of the integrated network architecture which combines XG-PON and enhanced distributed channel access (EDCA) under real time bursty traffic derived from the current global IP traffic distribution. The joint tuning of various crucial parameters of both XG-PON and EDCA with incorporation of an efficient deficit dynamic bandwidth algorithm (DBA) at optical line terminal (OLT) is done by exhaustive simulations in network simulator-3 (NS-3). Through intensive simulations and tuning, we are able to achieve a end-toend delay performance of < 150 ms for voice, < 500 ms for video and a few seconds for BE upto full capacity. Also, a packet loss ratio (PLR) of < 3% and < 6% is achieved for voice and BE respectively upto full load. For voice PLR is < 1% upto 60% total offered load. Further, it is observed that the fine tuning of key parameters has also resulted in increased bandwidth for dominant BE services. Therefore, this optimized network architecture is 20% more fair to BE services as compared to the conventional integrated FiWi architectures.

“…In contrast, random access is more suitable for dense networks because of its flexible access method. An improvement on the EDCA scheme in dense scenarios is introduced in [5]. The author extended the EDCA queue from 4 to 7 in order to assign priorities to various video traffic (HD, 4K/8K video).…”

OFDMA, introduced by the IEEE 802.11ax standard, divides the channel into multiple resource units (RUs), enabling parallel access for multiple users. On this basis, we propose a QoS-oriented double arbitration random access (Q-DARA) scheme. This scheme ensures high-priority priority access through priority arbitration in the first phase and random code arbitration in the second phase. It can also greatly reduce collisions and effectively guarantee the QoS of high-priority traffic. Simulation shows that our proposed scheme has better performance on throughput and latency. Compared to the traditional EDCA, the throughput and latency increase by more than 70%. Compared to the PATB scheme, the throughput increases by about 20%, and the latency increases by about 23%. Moreover, our proposed scheme has almost no changes to the protocol and is suitable for 802.11ax and beyond.
