近年來網路多媒體應用日漸盛行，從聲音、影像到網路電視的應用，皆流行於人們的生活之中。我們可以使用Skype 軟體撥打免費的網路電話或是節費電話，我們也可以使用軟體透過網路來觀賞電視節目，而大部分這類型的應用軟體皆使用點對點的技術來獲取更好的傳輸效率。點對點技術同樣是一項新的、受歡迎的應用。從一開始使用者使用點對點傳輸軟體來下載檔案、分享資料，到現在使用點對點傳輸軟體來收聽音樂、觀賞電視節目。無線網路，特別是IEEE 802.11 無線網路，近年來同樣地受到使用者的廣泛使用。使用者可以在任何一處使用網路，即使是在行走之中使用。多媒體結合無線網路是一項非常好的應用，然而，無線網路的一些基本問題，例如移動、傳輸不穩定，常常會降低網路的傳輸效率。因此，我們提出一個新的移動式點對點串流協定，來解決無線網路上多媒體應用的傳輸問題，讓影音的撥放可以更順暢。
Network multimedia applications are popular in recent years. From voice over IP, video over IP, to IPTV, they are in people’s life now. We can use Skype to dial a free network call or a cheap PSTN call, and we can use some
applications to watch TV programs from Internet. Most of them use peer-to-peer technology to get better performance. Peer-to-peer technology is also a new and popular technique in recent years. People use peer-to-peer software to download files and share data in the beginning, and now they use peer-to-peer software to listen to music, and to watch TV programs. Wireless networks, especially the IEEE 802.11 network, is also popular now. People can access Internet anywhere even they are walking. It's a good idea to use multimedia streaming applications in wireless networks, but however, the essential problems of wireless networks will reduce the performance of these applications, such as mobility, and channel instability. We propose a new
mobile peer-to-peer streaming protocol to solve the performance problems caused by wireless networks and let the media be played more continuously and smoothly.
