Current network situation with its limited resources and excessive users' demands reveals the potential necessity for revolutionary organization and management of these resources. Efficient and effective resource scheduling significantly reduces queuing delay which considered as crucial particularly for sensitive packets such as real-time application. This study investigates in the main four categories...
In this paper, we consider the important aspect of quality of service (QoS) in wireless mesh networks, focusing on packet delays and packet drops. We observe that the options of solely focusing on throughput, and of only depending on the QoS type characterization by the application level protocol is not sufficient. We propose the use of multiple queues to hold the packets based on their QoS requirement...
This paper describes an approach which uses a machine learning model in a packet scheduling problem to improve the end-to-end delay. A good Packet scheduling discipline allows to achieve QoS differentiation and to optimize the queuing delay. In a dynamically changing environment this discipline should be also adaptive to the new traffic conditions. We model this problem as a multi-agent system which...
This paper presents a comprehensive system modeling and analysis approach for both predicting and controlling queuing delay at an expected value under multi-class traffic in a single buffer. This approach could effectively enhance QoS delivery for delay sensitive applications. Six major contributions are given in the paper: (1) a discrete-time analytical model is developed for capturing multi-class...
High speed downlink packet access (HSDPA) was introduced to UMTS radio access segment to provide higher capacity for new packet switched services. As a result, packet switched sessions with multiple diverse traffic flows such as concurrent voice and data, or video and data being transmitted to the same user are a likely commonplace cellular packet data scenario. In HSDPA, radio access network (RAN)...
4G will introduce additional wireless networks offering faster data services. Service balancing is a technique where traffic overflows between wireless networks in order to improve QoS goals in an automated way. Since speech and queued packet data form the predominant services of the future, this study evaluates two techniques of overflowing services between radio access networks. To ensure response...
Adaptive resource management has become a key technique for the next-generation wireless systems to provide desired services at appropriate QoS. Most of the current resource management algorithms are confined to a single layer of the network protocol stack, which leads to an inferior performance. In this paper, we propose a joint MAC-PHY layer resource management algorithm for wireless OFDM networks...
