Nowadays, video streaming causes traffic over the Internet. Dynamic Adaptive video Streaming (DAS) has emerged as a promising solution. However, existing researches in DAS focus on single client instead of multi-client which is much closer to reality. Even if some methods are proposed for multi-client scenarios, they need to add coordinate proxy to the network or add additional function to routers...
The distribution of base stations has a great impact on interference distributions, while most of works about resource allocation are based on ideal assumptions. Base stations (BSs) are placed ideally and interference is ignored, which is far from the real scenario. In this paper, a structure of perturbed triangular lattice which is closer to the deployment of real base stations is proposed. Compared...
Quality of Experience (QoE) is a widely used metric reflecting the users' satisfaction of the multimedia service. This paper studies the QoE-driven resource allocation technique in the Orthogonal Frequency Division Multiplexing (OFDM) system. Different from other schemes, multiuser-multiservice scenario is taken into consideration for both power allocation and subcarrier scheduling, which is much...
Realizing the close connection between Customer Experience (CE) and profitability, the communications industry has been placing more and more attention to CE and Quality of Experience (QoE). The traditional Service Quality Management mainly focusing on Quality of Service (QoS) aspect no longer satisfies service providers' demand for taking the quality perceived by the customer into consideration....
When deploying large scale of QoS guaranteed IP-TV services over Triple-Play networks, there is a growing demand to access to the live network services, monitor in real time the broadcast chains, acquire the dynamic network parameters to ensure an uninterrupted, high quality service. Considering the difference of IP packet switching network and the de-facto transport stream (TS) standard of broadcast...
