Increasing use of real-time applications over IP networks will require better use of available resources to meet the stringent requirements of real-time applications, especially over the wireless links. When performing data linkhetwork layer scheduling, priorities of different realtime packets can be differentiated by exploiting the information available from a higher layer of the protocol stack (RTPRTCP). Utilizing the fast power control feature available in CDMA-based wireless networks, a packet scheduling algorithm'for real-time traffic over an IP-based cellular network was designed and evaluated. By utilizing the channel state and deadline information, much improved performance in transport of real-time traffic was achieved.different QoS schemes. Applications requiring better than best effort service over the Internet have been increasing over the years, and the effort to provide the necessary QoS guarantees has been an active area of research [3] [4]. Providing similar guarantees on bandwidth, end-to-end delay, delay jitter, and packet loss in a wireless network has been more challenging due to unique physical problems of the wireless channel such as limited bandwidth and high bit error rates (BER). Numerous MAC protocols have been proposed to deal with the expected demand for multimedia services over the wireless network [5] [6]. However, in these work the wireless link was studied separately from the rest of the network. The focus of these studies has been on the link-level performance rather than on end-toend performance.
