MIND Terminal Auto-adaptability to Achieve a Better User-Perceived QoS in Networks beyond 3G
نویسندگان
چکیده
Adaptive applications are a key concept to take into account when dealing with multimedia internetworking in wireless and mobile environments in which abrupt changes in the network conditions may occur. Using adaptation techniques at application layer is one of the solutions that allow multimedia applications to minimise the impact of vertical handovers in their performance, so that QoS perceived by the user remains in an acceptable level. This can be characterized by means of some tests and their empirical results.

Paving the road to systems beyond 3G - The IST BRAIN and MIND projects
Wireless LAN technology is complementary to 3G systems and could be used to provide high bandwidth hot spot coverage, for example in railway stations and offices, in order to provide the high bandwidth video and broadband services such as those emerging on DSL fixed access. The IST Projects BRAIN and MIND have investigated a number of key technical enablers for such a “system beyond 3G”. These ...

An important performance aspect of widespread networks is the quality of perceived conversational speech of voice calls and data services. Today these networks belong to 2-2.5 generation. Third generation (3G) networks were created only in the last decade. Currently 3G technologies are standardized. Equipment manufactures and network operators are in the process of deployment of 3G networks. Sc...

Present 3G capability to cater for subscriber demand for high data rate and QoS [Quality of Service] is substantially less than 4G networks. It is expected that 3G networks will not be able to meet the needs of services like video-conferencing, full motion video etc in terms of QoS. 4G networks provide subscriber with a higher bandwidth (5GHz), and mobile data rate greater than 100Mbps. However...
