Example 1: HiFi Sound
High-quality sound files too large to download and play over wireless link in real-time
Compression possible, but tradeoffs:
- sound quality
- overhead in compression/decompression
Idea: dynamically adjust compression level to available bandwidth, taking capabilities of mobile host into account
Information required from QoS API:
- mobile host CPU and speed, maybe even load
- link bandwidth, delays, error rates
Adaptive application, but no dynamic partitioning
