We study engineering and business relationships between Content Providers and broadband access ISPs in various organizational and policy environments. We focus on pricing and capacity decisions for bandwidth and caches for delivery of the CP's content over the “last mile” of the ISP's infrastructure. We model the CP-ISP interaction by the Stackelberg “leader-follower” game and the Integrated Operations...
Visible Light Communication (VLC) has become popular for its feasible and reliable speed and anti-jamming features. In fact, the structure of the transmission system for commercial usage has mainly limited the VLC transmission to downlink. To achieve higher transmission rate, a proper design of transmission constellation should be designed according to channel condition. In this work, we develop a...
To reduce network energy consumption without losing system performance is a key technique in 5th generation wireless communication systems. The on-off control in multi base stations scenario is proved a mixed dynamic integer programming problem and is hard to be solved. In this work, we provide a novel energy aware dynamic on-off control method in multi-base station scenario to tackle this problem...
With the increasing demand of transmission speed and more robust quality of service, the capacity constrained backhaul gradually becomes bottleneck in cooperative wireless networks, e.g. in Joint Processing mode of LTE-Advanced Pro. This paper focuses the fact of resource allocation with limited backhaul capacity in uplink cooperative networks, where two base stations (BS) equipped with single-antenna...
The prediction of traffic matrices (TM) is critical for many IP network management tasks. With the recent development of high-speed traffic measurement technologies, complete TM could be collected from operational IP networks. In this paper, we report our efforts in predicting the TM measured from a real IP backbone network in China. The new problem here is how to deal with the rich but noisy TM data...
To resolve problems that the metrological department is short for test equipments of high-voltage switch characteristic tester at present, the calibration technique is relatively backward, and its measuring precision is comparatively low, this paper uses the advanced technologies such as Micro-processor and integrated circuit to check for the time parameter of the high-voltage switch characteristic...
The magnetic susceptibility (χ) carried by pedogenic fine‐grained ferrimagnets has been widely used as paleoclimatic proxy to elucidate long‐term paleoclimatic variations for wind‐blown terrestrial loess/paleosol sequences. However, the magnetic properties of the lithogenic parent material can mask the pedogenic signals. In this study, we systematically investigated the origin of the superparamagnetism...
