The problems in the Covid-19 pandemic have a major influence on the field of education with the use of technology to support the teaching and learning process to facilitate students who do home learning activities. The proposed concept of freedom of learning is a more comprehensive concept such as portfolio and assignments such as group assignments, writings, and so on that are done in full online...
The availability and reasonable cost of broadband Internet made it an attractive and favourable option to billions of users worldwide. Being a fast service also encourages its users to use real-time applications which is streaming and live data transfer includes VoIP and video streaming. The performance of such applications in Wireless Local Area Network (WLAN) may be highly affected by security protocols...

Although, it was shown that NC is a promising technique to improve the throughput; especially for multicast environment; it also bears negative side-effects (e.g., high decoding delay). Since streaming video are usually subject to strict delay constraints, high decoding delay must be resolved to enhance the performance of the NC schemes. To overcome this issue, this paper presents a new scheme named...
Currently and due to its wide use, the wireless networks in conformance with IEEE 802.11 standard are generating channels saturation, that provokes interference between themselves. IEEE 802.11n is one of the standards that offers greater benefits to improve the wireless network performance. In this paper we analyze the performance of wireless network in conformance with IEEE 802.11n standard to evaluate...
In this article, we analyze the performance evaluation of WiFi technology in conformance with IEEE 802.11b/n/ac standards and Wireless Distribution System (WDS) for indoor environments with and without obstacles. We present different scenarios by varying the distance between transmitter and receiver. We analyzed the performance of the network by using the intrusive technique of traffic injection with...
The growing of the internet use is proportional with the growing of IP address needs, but the increasing of the IP use is not equal with the number of available IPv4. Then, IPv6 was developed as a solution to overcome the limited amount of IPv4 address. Readiness of various aspects ranging from infrastructure to a service provider is required to implement IPv6. In order to improve the quality of IPv6...
Long Term Evolution (LTE) is a standard proposed by 3GPP (3rd Generation Partnership Project) which capable of enhancing the performance of wireless system. However, fulfilling the indoor service requirements by extending the LTE coverage is insufficient since it is very difficult for the network operators to provision the QoS in the building. Hence, the deployment of Femtocell which complements the...
Mostly real time applications want rapid data transmission in the network. The performance can be ensured by mechanisms which gives performance by shaping and policing of packet traffic. Further improve the performance of the network by fair allocation of resources. Many congestion control techniques provide good fairness and throughput, which decreases the loss of packet. We have analyzed the strength...
Long Term Evolution (LTE) is a broadband wireless technology that promises to high throughput. In order to simultaneously support several mobile users with real time and non-real time applications, the resource management and Quality of Service (QoS) requirements of delay-sensitive traffic should be carefully aware. In this paper, The Delay-Aware with Resource Block Management Scheduling Algorithm...
This paper deals with quality of service (QoS) for triple play, mainly focused on voice and video. For studying changes in quality parameters at different network utilization, was it necessary to simulate LTE networks. For this purpose, the Matlab was chosen, in which we focused on the throughput. We simulated technology in particular scenarios, we changed the frequency and time division duplex, SNR,...
Usage of wireless networks is rising in popularity. In this setting different kinds of networks for indoor environments, such as Ad-Hoc, IEEE 802.11b (Wi-Fi) and Wireless Distribution System (WDS) has been developed. In this paper, an analysis of Quality of Service (QoS) has been made for each network in order to verify the values of bit rate, delay, jitter and packet loss. For performance comparison...
Many applications of wireless sensor networks (WSNs) need to balance multiple yet often conflicting performance requirements such as high energy efficiency, high throughput, low delay and low loss. Finding appropriate WSN parameter configuration to achieve the best trade-off requires in depth understanding of the joint effect of key parameters residing at different layers on the performance. In this...
A volcano monitoring system plays a key role for launching emergency early warning, and the use of alternative technologies have proven their effectiveness in this setting, which is the case of wireless sensor networks. For surveillance systems, the real-time requirement is mandatory due to the need for immediate access to the signals derived from a natural disaster where the goal is safeguarding...
Cloud computing is becoming commonly used for enterprise systems. Users utilize WAN, the Internet, or a wireless network to access the cloud service. These networks often have large RTT and packet loss ratios (PLR), so if users communicate via TCP widely used for accessing cloud services, the throughput decreases and the access quality of the cloud service deteriorates. Therefore, much TCP acceleration...
3G networks penetration is increasing in China, particularly on mobile devices, but little is known about the performance in the country. In this paper, the WCDMA and CDMA's uplink broadband performance was measured in Nanjing. Content of the measuring include throughput, packet loss, delay and receiving interval. Through testing, we can identify the relationship between uplink packet loss, delay...
Since wireless sensor nodes are battery powered, the emphasis was on reducing the energy consumption of the sensor nodes. However, with the increase in real-time traffic requirements in wireless sensor nodes, network performance metrics are increasingly important. Nonetheless, most existing network performance studies were done via simulation, with few experimental studies performed on testbeds using...
Video streaming is the real time delivery process of video to the user's media player services. In multimedia streaming technique, the user can access data while it is being transferred. To meet the demand of providing high-quality of video streaming, it is important to design suitable QoS model. Hence, in this project, we designed around streaming services using an Internet topology on expected video...
A Carrier Ethernet Network (CEN) is a versatile, standardized, ubiquitous, carrier-class network. It possess several attributes that distinguish it from Metro Ethernet Networks (MENs), quality of service (QoS) being an integral one. Because CENs are designed to cover large areas (thousands of km) and transmit at high data rates (100 Gbps), these networks have a high bandwidth-delay product (BDP)....
Network coding is a new area of networking, in which data is processed inside the network to increase throughput, to balance traffic load and to save bandwidth of a network. Network Coding performs well in lossy wireless networks in both multicast and broadcast scenarios. Even in wireless networks with low density of nodes network coding performs well using its multi-copy packet transmission scheme...
