Real-time distribution of stored video over wide-area networks is a crucial component of many emerging distributed multimedia applications. The heterogeneity in the underlying network environments is an important factor that must be taken into consideration when designing an end-to-end video delivery system. In this paper, we present a novel network-conscious approach to the problem of end-to-e...

A complex network is a useful tool for representing and analyzing complex systems, such as the world-wide web and transportation systems. However, the growing size of complex networks is becoming an obstacle to the understanding of the topological structure and their characteristics. In this study, a globally and locally adaptive network backbone (GLANB) extraction method is proposed. The GLANB...

Providing Quality of Service (QoS) is a major challenge in wireless networks. In this paper we propose a distributed call admission control protocol (DCAC) to do both bandwidth and delay guaranteed call admission for multihop wireless mesh backbone networks, by exploiting the multi-channel multi-radio (mc-mr) feature. We propose a novel routing metric for route setup, and present an efficient d...

In this paper, we propose an end-to-end quality of service (QoS) adaptation network architecture to guarantee service qualities for mobile users, according to user requirements and available network resources on the end-toend path which is across the wired backbone DiffServ network and wireless IntServ networks. Further, we adopt the bandwidth broker (BB) for resource allocations and COPS-SLS p...

The Internet is perhaps the defining technology of the emerging twenty-first century. This article examines the infrastructure that comprises the “network of networks” and the spatial patterns that have emerged in the Internet’s short existence. In its brief history, the Internet has manifested a tentative relationship with the urban hierarchy. This relationship is tracked over a four-year peri...

Service discovery architectures and clusterassisted routing protocols in mobile ad-hoc networks (MANETs) heavily use formation and maintenance of a virtual backbone (VB), where the most stable mobile nodes with higher node degree are dynamically selected as the backbone nodes. In this paper we present a novel analytic model for VB stability in MANETs. The model employs the dynamics of node move...

Personal Communication Network (PCN) is an emerging wireless network that promises many new services for the telecommunication industry. The high speed backbone network (ATM or WDM) is one possible approach to provide broadband wireless transmission with PCN's using the ATM switching networks for interconnection of PCN cells. The wireless ATM backbone network design problem is that of allocatin...

Much research and development related to digital video has targeted storage, wired backbone, and broadcast wireless transport environments. Here we address video transport in a heterogeneous network, especially with interference-and fading-dominated wireless access, such as a cellular local-area or wide-area network. It is expected that multimedia (including video) will be an important applicat...

Temporal networks refer to like physical contact whose topology changes over time. Predicting future temporal network is crucial e.g., forecast the epidemics. Existing prediction methods are either relatively accurate but black-box, or white-box less accurate. The lack of interpretable and motivates us explore what intrinsic properties/mechanisms facilitate networks. We use learning algorithms,...

In this paper, we present a panorama picture on how to achieve end-to-end video over IP service under the communication environments, consisting of backbone networks, hybrid access networks, and the end users. The paper consists of three equally weighted subtopics which cover some novel thoughts in designing and implementing the video over IP system in the different areas, namely, a Synchronous...
