Proxy-driven streaming service in Wireless Multimedia Service Zones (WMS Z) is challenging due to rate distortion and high channel error rate. To facilitate proxy-driven streaming media services in wireless multimedia service zones, streaming operations such as distortion detection, distortion adjustment, and caching management should be considered. A new Proxy-Driven Streaming Service (PDSS) is proposed to support high streaming quality in IEEE 802.11-based wireless multimedia service zones. The proposed mechanism performs disjunction mapping-based management operation, conjunction mapping-based management operation, and filer mapping-based management operation to derive the optimized proxy caching for the individual versions of a media object.
