Wireless Video Streaming
Goal: Flexible networking protocols in support of error resilient video codecs
GSM RLP: reliable data delivery on radio link
- Issue: reliability versus delay
UDP Lite (existing protocol)
- Flexible checksum allows app to receive corrupted data
RLP Lite (new protocol)
- Same as UDP Lite, but for radio link
Simulation/experimental results: UDP Lite/RLP lite
- less E2E delay, constant jitter, higher throughput, lower packet loss
- … than UDP (with or without RLP)
Collecting radio traces is time consuming
- MTA – Markov-Based Trace Analysis Algorithm
- Mathematical channel models based on empirical trace measurements
- Enables generation of artificial traces with same statistical characteristics as real traces (BER, burst error length, etc)
