The local and premises wireless networks have been expanding into many areas. The core network access point or basic station infrastructure can be made on wireless systems, on fixed cable systems with metallic twisted pairs, and, prospectively with optic fibers. The VDSL2 line systems with VDMT modulation and line bounding will be used for a data speed of hundreds Mb/s and distance between acti...

It has been shown that an agent located at the junction of wired and wireless links can help streaming media systems identify where packet losses occur and therefore maintain proper endto-end congestion control. In this paper, we further expand the functionality of such agents in two ways. First, they allow streaming servers to identify the allowed transmission rate in both the wired and wirele...

Rate Control plays an key role for many multimedia services such as streaming applications. These streaming applications such as video on demand (VoD) or voice over IP (VoIP) services face some critical problems such as insufficient bandwidth and improper performance of transmission protocols. Emerging real-time multimedia services over IP grow fast with the advent of advanced broadband communi...

Many of us have been watching the recent goings-on at Netscape and wondering what it all means. The layoffs in general, the cancellation of in-house Java development, and the Communicator source-code giveaway have received most of the attention, but another unsettling item has gone largely unnoticed. As of February 1998, Netscape no longer maintains a staff of usability engineers. At its zenith...

This paper introduces the concept of eigen-dynamics and proposes an eigen dynamics analysis (EDA) method to learn the dynamics of natural hand motion from labelled sets of motion captured with a data glove. The result is parameterized with a high-order stochastic linear dynamic system (LDS) consisting of five lower-order LDS. Each corresponding to one eigen-dynamics. Based on the EDA model, we ...

In this paper, we address the end-to-end rate optimization problem in a wired-cum-wireless network, where CSMA/CA based wireless LANs extend a wired backbone and provide access to mobile users. The objective is to achieve proportional fairness amongst the end-to-end sessions in the network. Since the network contains wireless links whose attainable throughput is ‘elastic’ and is a non-convex an...

The Internet has evolved from a wired infrastructure to a hybrid of wired and wireless domains. As network access is now provided with much of the last mile being a mobile environment, delivering rich multimedia to mobile users is now a necessity. However, despite the advent of new technology and standards for broadband wireless, there is still an important dilemma over the choice of systems th...

The internet is used for wide variety of applications in wired, fixed wireless and mobile wireless environment. The requirements of one application / environment will vary from another application / environment. The challenge for the service provider is Quality of Service (QoS). The wired network has less complexity compared to fixed wireless network with respect to QoS. Certainly, the challeng...

An Ad hoc network is a short-live network in which two or more mobile devices connected to each other without the help of intervening infrastructure. The routing protocols designed for wired networks are different from Ad hoc networks protocols because wired network can't work efficiently in Ad hoc networks. This imposes different design constraints and requirement on routing protocols for...

Many companies, organizations, and even individuals implement wireless local area networks (WLANs) in various locations such as their offices, conference rooms, homes, and business areas. This type of connection offers users portability because they can move from one location to another while maintaining access to the corporate network, but it does not offer access between locations. Mobility, ...
