Torus, which is simple and incrementally expandable, could perfectly fit the scale-out model of current large scale computing systems, such as data centers. However, on the downside, torus suffers from its long network diameter. One way to address this problem is using random shortcuts. However, this approach does not consider the variety of data center traffic, and leads to severe non-uniform network...
In this paper, we analyzed TCP performance in UWB WPAN by establishing UWB test-bed. Impact of asymmetry between forward link and reverse link was concerned. Furthermore, we analyzed relationship between TCP throughput and reverse link bandwidth. Our study demonstrated that available resource of reverse link impacts TCP performance seriously. In addition, it was found that there is an optimal reverse...
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...
Call admission control (CAC) is a key factor in quality of service (QoS) provisioning for multimedia service in modern network. Lots of CAC schemes aim to satisfy QoS requirement and upgrade network utilization, but they ignore the fairness principle in network. Directly and simply using these schemes, it will appear the phenomenon that the narrow band calls block the broad band calls. The common...
