Fiber-wireless integrated networks that rely on the collaborative use of both fiber-based and wireless communication technologies are currently turning into a highly important research area in view of...
We consider a multi-period variation of the network utility maximization problem that includes delivery constraints. We allow the flow utilities, link capacities and routing matrices to vary over time...
This paper quantifies the shift in the household-level demand for postal delivery services over time and determines the extent to which it can be attributed to the appearance of alternative modes of...
Rice University engineers have demonstrated the first system that allows wireless data transmissions over UHF channels during active TV broadcasts. If the technology were incorporated into n...
A revolution in network connectivity is leading us towards the NextGeneration Network (NGN) era with novel types of services which aredriven by two trends: user-centric, End-to-End (E2E) service deliv...
DTN(Delay-Tolerant Network)是人们在近年出现的众多网络实例中抽象出来的网络模型。在这种网络模型中,经常出现长时间的网络分割,以至于在给定的时间段内端到端的路径不一定存在。由于DTN这种独特的拓扑性质,其路由机制和传统的网络模型有很大不同。该文详细研究了DTN的一种路由算法ED(Earliest-Delivery)算法,然后引入了对节点运动精确性(相对于时间)的考虑,给出了...
This paper presents a novel data organizing and delivery framework for P2P media streaming which is aware of media content. In this framework,the media data is partitioned GOP by GOP, and reorganized ...
Scalable streams provide a layered representation for transmitting media contents over a channel with packet losses and variable delay. In general, real-time streaming scalable media to audience has ...
