Abstract :
The advances in wireless digital communication technology due to the development of digital cellular telephony, the rapid growth and popularity of the multimedia rich World Wide Web, together with the availability of multimedia compression hardware and software have helped to push wireless multimedia communications to the forefront in the area of communications.

The objective of this large project is to develop enabling technologies and tools for reliable multimedia wireless communications. Such techniques must be able to provide guaranteed quality of service (QOS) to real time multimedia traffic in a wireless and mobile radio environment. In particular, sharing the available resources efficiently among the users as well as among the different types of traffic while meeting different quality requirements with bursty traffic in the harsh wireless environment are important tasks for future multimedia communications networks. Other factors which will be addressed include multiple access and channel access for the various bursty traffic types, multipath fading and shadowed mobile environments, bandwidth efficiency, co-channel interference, low power battery requirements, multimedia compression algorithms, and efficient video and speech coding techniques in wireless environments. Finally, a test bed which will demonstrate the feasibity of the developed techniques will also be built.
