. It presents mobility scenarios in a special DVB-T environment, along with a complete broadcasting architecture, in which all leading mobile technologies coexist, and provides solutions and enhancements for a better technology deployment.

Abstract: Contemporary DVB-T networks, when combined with wireless data links for the interaction data, can provide an effective and affordable solution for Internet and data service provision to portable and mobile end users. This paper presents the performance of TCP in a hybrid DVB-T

Emerald is an object-based language and system designed for the construction of distributed programs. An explicit goal of Emerald is support for object mobility; objects in Emerald can freely move within the system to take advantage of distribution and dynamically changing environments. We say

) [6] and is intended to provide standard specification for interactivity in the UHF/VHF bands. Using the newly defined DVB-RCT standard as a companion of the world-wide proven, recognised and adopted Terrestrial DVB system [3], DVB-T is no longer limited to unidirectional broadcast, it can become a

The reception of the DVB-T signal on a mobile equipment is strongly affected by Doppler spread. Most of the current proposals require the use of two or more antennas at the receiver and a computationally expensive signal processing. In this paper for a DVB-T receiver with a single antenna we

simple task, due to the many differences of those two in the way of handling particular domains, such as multicasting, mobility, and quality of service. Also, there exist several kinds of DVB technologies, DVB-S for Satellite, DVB-C for Cable, DVB-T for terrestrial, each one with its own specifications

it supports concurrent execution of diverse mobile applications. We identify agility as a key attribute of adaptive systems, and describe how to quantify and measure it. We present the results of our evaluation of Odyssey, indicating performance improvements up to a factor of 5 on a benchmark of three

, scalability, and customizability. To address these issues, researchers are investigating a variety of innovative approaches. The most promising and intriguing ones are those based on the ability of moving code across the nodes of a network, exploiting the notion of mobile code. As an emerging research field

Mobile ad hoc networks have gained a lot of attention lately as a means of providing continuous network connectivity to mobile computing devices regardless of physical location. Recently, a large amount of research has focused on the routing protocols needed in such an environment. In this two

This paper describes a self-organizing, multihop, mobile radio network, which relies on a code division access scheme for multimedia support. In the proposed network architecture, nodes are organized into nonoverlapping clusters. The clusters are independently controlled and are dynamically
