“…Their analysis without hidden node problem show that interference among nodes can be reduced to maximize throughput by using the smallest transmission range and the achievable per node throughput is 11% of the channel capacity. The authors in [17] have considered the effect of QoS application on the IEEE 802.11n based uniform (or single hop) topology performance. For 18-node uniform topology with 4x4 spatial streams, their results show that when QoS is applied the maximum improvement values are 91.6% and 34.8% for throughput and delay respectively.…”

The IEEE 802.11n supports high data rate transmissions due its physical layer Multiple Input ‎Multiple Output (MIMO) advanced antenna system and MAC layer enhancement features (frame ‎aggregation and block acknowledgement). As a result this standard is very suitable for multimedia ‎services through its Enhanced Distributed Channel Access (EDCA). This paper focuses on ‎evaluating the Quality of Service (QoS) application on the performance of the IEEE 802.11n ‎random topology WLAN. Three different number of nodes (3, 9 and 18) random topology with one ‎access point are modeled and simulated by using the Riverbed OPNET 17.5 Modular to ‎investigate the Wireless Local Area Network (WLAN) performance for different spatial streams. ‎The result clarified the impact of QoS application and showed that its effect is best at the 18 node ‎number topology. For a 4x4 MIMO, when QoS is applied and with respect to the no QoS ‎application case, simulation results show a maximum improvement of 86.4%, 33.9%, 52.2% and ‎‎68.9% for throughput, delay, data drop and retransmission attempts, respectively. ‎

“…The IEEE 802.11 standard, which manages the implementation of wireless local area networks, has also fundamentally proliferated in all sectors owing to its installation simplicity [4,5]. Furthermore, the IEEE 802.11 standard has received numerous enhancements, which has subsequently led to IEEE 802.11 standard enhancements [5,6]. In the previous 802.11 standards, the physical (PHY) and medium access control (MAC) layers had experienced several upgrades, including the introduction of multiple input multiple output (MIMO) technology at the PHY layer, and the doubling of the channel bandwidth (BW) to 40 MHz with the orthogonal frequency division aggregation (MIMO-OFDM) and the MIMO technology.…”

The widespread and desirable features of IP and IEEE 802.11 networks have made these technologies a suitable medium for carrying voice over IP (VoIP). However, a bandwidth (BW) exploitation obstacle emerges when 802.11 networks are used to carry VoIP traffic. This BW exploitation obstacle is caused by the large 80-byte preamble size of the VoIP packet and a waiting time of 765 μs for each layer 2 VoIP frame. As a solution, IEEE 802.11n was consequently designed with a built-in layer 2 frame aggregation feature, but the adverse impact on the VoIP performance still needed to be addressed. Subsequent VoIP research has proposed numerous enhancements to the built-in IEEE 802.11n aggregation techniques. In this study, we analyse and propose enhancements to the BW exploitation and VoIP performance over IEEE 802.11n. We also recommend new techniques to enhance VoIP performance via IEEE 802.11n frame aggregation implementations. Furthermore, we contribute guidelines for creating a robust, suitable, and reliable aggregation technique for VoIP over the 802.11n standard.
