Improving the performance and reliability of wireless in mobile streaming media

Delivering media to large numbers of mobile users present challenges due to the stringent requirements of streaming media, mobility, wireless channels and scaling, to support large numbers of users. In this paper, we study the major sources of packet delay in the GPRS wireless network. The wireless channels may be shared by other users, and may be afflicted by interference which leads to packet delivery over lossy channels and busy channels. We study the packet delay and channel sharing across the air interface of GPRS systems, based on channel availability.
