SCAP: Smart Caching in Wireless Access Points to Improve P2P Streaming

The increasing number of wireless users in Internet P2P applications causes two new performance problems due to the requirement of uploading the downloaded traffic for other peers, limited bandwidth of wireless communications, and resource competition between the access point and wireless stations. First, an active P2P wireless user can significantly reduce the downloading throughput of other wireless users in the WLAN. Second, the slowdown of a P2P wireless user communication can also delay its relay and data sharing service for other dependent wired/wireless peers.
