The rapid introduction of new mobile data services presents many challenges to wireless service providers. Unlike voice services, whose traffic characteristics are well understood, new data services are far more volatile and their demand on network resources is harder to predict. Data volumes are exploding and impacting not only the ability of the network to support such traffic but are also driving...
With the advances in wireless technology and explosive growth of mobile devices and wireless networks, mobile TV is becoming a popular application. The main technical challenge to wireless video broadcast is to provide the best quality of service possible under the radio resource constraints. In this paper we propose an application layer middleware solution that utilizes the scalability in video coding...
Current mobile devices are often equipped with several network interfaces, which may be of different access technologies, both wireless and cellular. As a result, many networks are evolving to serve diverse communication needs. These networks are increasingly interoperable and based on IP architectures. Wide area networks, with pervasive coverage in many parts of the world, are forming the basis for...
The improved processing power and battery life of mobile devices, as well as the near ubiquitous coverage of wireless data communication networks allow mobile users to use information services in a similar way to desktop users. People not only demand access to existing Internet services from their mobile devices, but also to have available new services specifically designed for mobile environments...
