| Popis: | 94 For supporting handoff mobile users on heterogeneous wireless networks to synchronously receive and play out multicast multimedia stream data, we propose a two-layer Hierarchical Synchronized Multimedia Multicast (HSMM) architecture to enhance capabilities of the single-layer Synchronized Multimedia Multicast (SMM). In HSMM, each wireless network operator can adapt its own management mechanism, such as routing protocol, access control, etc., and further define the range of Guarantee Region to satisfy different management requirements. Compared to SMM, HSMM will significantly reduce total amounts of synchronization buffer of foreign agents, and achieve a better playback quality. |
