This work investigates the access point (AP) selection problem in Variable channel-width WLANs (V-WLANs) using an evolutionary game-theoretic approach. A practical utility function is designed for each station in which the QoS requirement and energy consumption are considered. An Evolutionary Stable Strategy (ESS) of the game corresponds to the desired AP selection outcome, which remains stable even...
In this paper, we proposed a new approach, based on principal component analysis (PCA), to evaluate user satisfaction of packet service in GPRS network. Based on our experiment, correlations between different QoS parameters are provided. At the same time, a PCA based user satisfaction factor is defined which reflects the user experience.
In this paper, resource allocation for mixed traffic in wireless access networks is investigated and a utility-based resource dynamic allocation (URDA) algorithm is proposed. This algorithm considers the QoS characteristics, real-time resource requirements and wireless channel states that belong to different types of applications, and then generates utility functions of them. The resource is allocated...
In wireless personal area networks (WPANs), a successful design of scheduling scheme is critical for video traffic in QoS guarantee and efficient channel resource utilization. In this paper, we propose a novel cross-layer scheduling scheme for MPEG traffic in high speed WPANs. The scheme aims at introducing robust improvements to MPEG traffic scheduling by taking most advantages of traffic characteristic...
