一种考虑QoS的多媒体业务跨层设计

Cross-layer Design Considering the Multimedia Services of QoS

现有跨层设计主要考虑2层联合设计,且在一个物理帧中只能插入一种业务类型,其功能和效率都受到限制。针对该问题,采用结合应用层的多层联合设计保证业务QoS要求,实现一个物理帧中插入多种多媒体业务类型。通过仿真验证了采用跨层设计方案的可行性,同时验证了该系统性能的优越性。

Currently,most cross-layer design used joint two-layers design,and it could only insert one class of service in a physical layer frame,which introduced functional and efficiency limitations.Combining with application layer,a multi-layer design architecture was proposed.This scheme could provide QoS guarantees and insert more than one class of multimedia services in a physical layer frame.The performance results of the scheme showed that the cross-layer design was applied and the system performance was improved.
