Many network devices, such as a smartphones and tablets, and streaming services, such as YouTube and Netflix, have become widespread. This causes network‐bandwidth congestion, so users require stable and consistent communication quality. Call admission control (CAC) has been proposed to solve these bandwidth resource problems. Some CACs have been proposed in order to maintain QoS. However, these CAC does not assume user behaviour. If CAC assumes some user behaviour, optimal control parameter derived conventional CAC may change because traffic load change by considering user behaviour. This article assumes that arriving types of flows are of three types: narrowband flows, broadband flow without seek‐bar operation, and broadband flows with seek‐bar operation. Under this assumpution, two CAC methods with single threshold or two thresholds are proposed. With these methods, it is assumed that all arriving flows result in the same user satisfaction when accommodated in a network. Under this assumption, the maximum of each user satisfaction is the same as the maximum number of accommodated flows. Using the call loss probability characteristics of Method 1, the objective function in Method 2 is modified. By using the modified objective function, CAC can be realised while properly accommodating broadband users who have been excessively rejected.

“…Thus, various streaming application flows (flows) occupy network‐bandwidth. We need to control these flows, which have various required bandwidths to improve quality of service (QoS) [5]; therefore, QoS control is important when streaming flows are used.…”

“…A scheme to improves the QoS of multimedia transmissions is proposed by Kim et al [7] using an adaptive algorithm that switches between UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) based on the size of the data. Also, an important multimedia data segments are selected for retransmission using the Forward Error Correction (FEC) methodology to prevent the loss of packets during the transfer and to improve transmission efficiency.…”

Quality of Service (QoS) is becoming increasingly important with the rise of multimedia applications (such as voice over IP (VoIP), video conferencing, and so on) in public data networks. These applications demand real-time service, while the networks should still be able to transfer also other traffic reliably (e.g., data, email, and WWW). In this paper, we concern how to improve the QoS of multimedia applications (Voice and video traffic) in DiffServ internet router by using the reconfigurable technique. Therefore we design an QoS model called Reconfigurable Scheduling Model (RSM) for real-time traffic in Diffserv router. In this model, we use the strict priority technique for the voice traffic to reduce the delay and then improve the QoS. While for video traffic, a hardware reconfigurable technique is used to provide the flexibility that improves QoS levels when compared to other techniques such as software-only implementations. This permits the run-time reconfiguration of the router resources, i.e., to change their functionality (from one scheduling algorithm to another), to adapt the fluctuation in traffic parameter. We choose two of the most widely used schedulers (CBWFQ, and MDRR) to support real-time allocations and to improve the QoS of video traffic. The reconfiguration or the switching between those two schedulers is based on queuing delay of the video traffic. To evaluate the proposed approach, the queuing model was built and simulated with MATLAB Simevents and Stateflow components. The result of simulation shows an improvement in QoS of voice and video traffics.

“…In the next paper [13], entitled Transmission Algorithm with QoS Considerations for a Sustainable MPEG Streaming Service, Kim, S., et al propose and suggest a sustainable MPEG streaming method maintaining Quality of Service (QoS) standard. Their method is adaptive given that one UDP (User Datagram Protocol) and one TCP (Transmission Control Protocol) is selected based on the size of the data, which improves the reliability of multimedia transmissions.…”

Future Sustainability Computing (FSC) is a novel research topic that deals with algorithms, procedures, and applications of information technologies for abundant life. In this Special Issue, we cover novel research and applications within the scope of sustainability computing dealing with hardware/software technologies, especially for frameworks and architectures. For example, topics include dynamic group management in Internet of Things (IoT); real-time video surveillance; security threats in Software Defined Network (SDN); real-time indoor Air-Quality level indicator; effectiveness of information systems security; load-balancing for inter-sensor convergence; neighbor discovery in sensor networks; transmission algorithm with Quality of Service (QoS) consideration; analysis of the relationship between Intrusion Detection System (IDS) alerts and darknet are included.
