Cache Replacement Techniques for Streaming Media In Wireless Home Networks

Wireless home networks are widely deployed due to their low cost, ease of installation, and plug-and-play capabilities with consumer electronic devices. Participating devices may cache continuous media (Audio and Video Clips) in order to reduce the demand for outside-the-home network resources and improve the average delay incurred from when a user references a clip to the onset of its display (Startup Latency). This paper focuses on a home network consisting of a handful of devices. A device may manage its cache at the granularity of either a clip or individual blocks of a clip by employing either a clip-based or a block-based cache replacement technique.
