In this paper, we design a game theoretical framework for improving the Quality of Service (QoS) in cooperative RAN caching. Considering the cooperation under both single cell transmission and joint transmission, the QoS metric is uniformly quantified as the total content delivery time. Although the formulated cooperative content placement problem is proved NP-hard, noticing the local cooperative...
Today, how to accurately predict the quality of experience (QoE) of the networking service is a very important issue for the network operator to optimize the service. However, due to the complex multi-dimensional characteristics of QoE, QoE estimation is extremely challenging. With utilizing the advantages of quality of service (QoS) in evaluating the networking performance, we exploit QoS/QoE correlation...
Wireless mesh network (WMN) has recently emerged as a promising technology for next-generation wireless network. In WMNs, many important applications, such as audio/video conferencing and distance education, require the support of multicast communication with quality-of-service (QoS) guarantee. In this paper, we investigate the issues of QoS multicast routing in wireless mesh networks. The paper studies...
Wireless interference can make a significant impact on the performance of a wireless network. The paper studies TDMA-based timeslot allocation to schedule links efficiently under RTS/CTS interference model of wireless networks, and presents an efficient centralized timeslot assignment algorithm. In addition, the paper presents an effective heuristic algorithm for calculating end-to-end bandwidth on...
