Cross layer design is considered as an attractive strategy to enable multimedia transmission over cognitive ultra wide band (C-UWB) system experiencing time-varying channel conditions and traffic characteristics. The close dependency among various parameters across protocol stacks need to be addressed to determine the optimum cross layer approach. Hence, this paper highlights a MAC centric cross layer...
Enabling video transmission to be maintained at an acceptable level under unreliable and time-varying wireless channels in a non-trivial challenge. The main challenge in enabling video transmission over UWB WPAN lies on how to meet the QoS requirements (ie: delay, jitter, PSNR) under time-varying spectral resources, video frame dependencies, limited power and data rate and tight delay constraint....
There has been an alarming increase in demand for multimedia applications due to explosive growth in communication, commerce and entertainment services. Nowadays devices such PDA, laptops and phone have more processing and computing capability. Consequently, this will eventually allow more effective and efficient video streaming and mobile applications over wireless network. Perhaps the development...
