Performance analysis of dynamic packet scheduling within a CDMA2000 broadcast network

Abstract

cdma2000 1xEV-DO, one of the prominent third generation mobile communication systems, provides Broadcast and Multicast Services (BCMCS) to meet increasing demand for multimedia data services. We propose a dynamic packet scheduling algorithm that works with a retransmission scheme for the BCMCS scheduler. Integrated with EDF (Earliest Deadline First) real-time scheduling, the proposed algorithm not only adapts to dynamic contexts efficiently but also satisfies the real-time requirements of broadcast streams. Furthermore, by supporting handoff in this dynamic scheduling environment, we can reduce the discontinuity of service when a mobile node moves into a new service area. Extensive simulations have quantitatively verified the efficiency of our approach even when mobile nodes move around among many service areas. © 2005 IEEE.
