“…In research by Shreekant Gurrapu et al [17], the performance of various VoIP codes was compared and studied in non-mobility scenarios by adjusting some parameters and plotting the throughput, End-to-end Delay, MOS, Packet delivery Ratio, and Jitter graphs using Network Simulator version. Ziyad Khalaf Farej et al [18], evaluated the Quality of Service (QoS) application and its effect on the performance of random topology WLAN using IEEE 802.11n, according to the results, a maximum improvement of 86.4%, was shown for throughput, as well as 33.9% for delay, 52.2% for data drop and 68.9% for retransmission attempts.…”

In the modern landscape of telecommunication, wireless mobile connectivity and migrating voice telephone services to IP technology are two of the most prominent developments that are transforming the landscape. These two concepts can be utilized together using networks which carry voice services over wireless LAN (VoWLAN). However, due to the unique characteristics of each, certain issues inevitably arise and must be handled to allow for suc-cessful deployment. In this paper OPNET 14.5 Modeler was used to carry out extensive simulation scenarios to examine the single cell WLAN VoIP ca-pacity in regards to three IEEE 802.11 WLAN standards which are (a, b, and g) as well as applying different packet sizes, data rates and codec types for analysis.

For an efficient design of wireless local-area networks (WLANs), the simulation tools are important to accurately estimate the IEEE 802.11n/ac link features for WLANs. However, this true simulation of network behavior is critical in designing high-performance WLANs. Through testing, analysis, and modeling of the proposed scheme repetitively, the design of the WLAN can be enhanced with a small budget before making its practical implementation. Many network simulation tools have been established to give solutions for this request and ns-3 is the most widely used tools among them by the research industry as an open-source network simulator. In this paper, we examine the various link features of the 802.11n WLANs under several conditions. We investigate the effects of 802.11n WLAN modulation and coding schemes (MCSs), 20MHz single channel or 40 MHz bonded channel, guard intervals (GI), frame aggregation, data encoding, number of antennas and their data rate, and link distance features of 802.11n WLAN in ns-3 when only a unique host connects with the access point (AP) and generates data traffic. Besides, the performance for an enterprise scenario proposed by the IEEE 802.11ax study group is evaluated when several hosts are simultaneously creating traffic with their associated APs. The results demonstrate that ns-3 support most of the link features of the 802.11n protocol with significant accuracy.

The increase in the number of users on wireless local area networks (WLAN) and the development of large size applications have increased the demand for high-speed data rate and low latency. The IEEE 802.11ac was developed to provide very high throughput WLANs. Many enhancements are added to the medium access control (MAC) and physical (PHY) layers to increase data rate and improve network performance, these features enable the IEEE 802.11ac standard to provide quality of service (QoS) for multimedia applications. This paper concentrates on the impact of QoS on the system performance in term of delay and throughput. Four scenarios are proposed to investigate the network performance with different (from 1 up to 8) spatial stream (SS). The objective modular network testbed in C++ (OMNet++ modeler v5.5.1) is used to simulate and model these scenarios. For 8×8 SS, the results of simulation show the best throughput (maximum) and delay (minimum) values of (622, 484, 399.3, 382.96 Mbps) and (0.0211, 0.0589, 0.1037, 0.1202 sec) for 5, 15, 30 and 45 node number scenarios respectively. Although the number of nodes increases, the system performance decreases, however when QoS is deployed the performance is enhanced and its best improvement is obtained at the highest (45) node number scenario with values of 94.4% and 56.1% for throughput and delay respectively.
