Abstract
We consider the distribution of real-time multimedia content (e.g., radio or TV broadcasts) through multiple aggregators. An aggregator is an intermediary content provider that operates a pool of proxy servers to aggregate content from sources and forward it to mobile hosts. Aggregators package content into channels (e.g., CNN or ABC) and offer them in various versions (e.g., using different encodings) that differ in quality or price. Mobile hosts receive channels via the wireless Internet, which consists of multiple types of wireless networks (e.g. 802.11 and UMTS). At specific locations, mobile hosts can connect to multiple networks simultaneously (e.g., in a hotspot) and can thus potentially receive different alternative versions of a channel from different aggregators through different interfaces.
