Traffic load in the aggregate class of DiffServ network varies dynamically. However, when the traffic load proportion of different aggregate classes is not equal to the assigned weight proportion in the scheduling algorithm, such as the WFQ algorithm, the packets in different aggregate classes will receive unfair treatment, even though these classes have(More)
To reduce the fossil energy consumption and the operational expenses, the hybrid energy powered cellular network (HybENet) with BSs powered by on-grid or renewable energy is studied. To minimize the total expenses of energy consumption (EEC) and guarantee the quality of service of HybENet, a liquid cell management algorithm, which adaptively and(More)
In this paper, we propose a QoE Space (QS) based QoE Adaptation (QSQA) algorithm for SVC based peer-to-peer (SVC-P2P) video streaming systems. The QS records the users' experiences in terms of Mean Opinion Scores (MOS) with different content type, packet loss rate, spatial resolution, frame rate and video compression Quantization Parameter (QP). The two(More)
Due to the special topologies and communication pattern, in today's data center networks it is common that a large set of TCP flows and a small set of TCP flows get into different ingress ports of a switch and compete for a same egress port. However, in this case the throughput share of flows in the two sets will not be fair even though all flows have the(More)
With the fast-pacing deployment of wireless sensor network(WSN) services, service ranking becomes more and more important. However, current service ranking methods mostly ignore the physical-level quality variation, making service ranking inaccurate. To address this problem, in this paper we propose a novel QoS-based ranking approach for WSN services, which(More)
