隨著各類型大規模內容傳輸應用服務的蓬勃發展，P2P已成為現今的網路世界中不可或缺的重要技術。隨著無線網路的基礎建設日益普及化，在以上這些P2P串流系統服務支援行動性的也必須面臨一個挑戰。本論文簡單介紹了行動節點換手對P2P覆疊網路結構上的影響，亦針對P2P串流系統之行動節點換手造成的不穩定問題，提出一個隱藏行動節點換手之機制，當行動節點變動IP時，使原有的P2P結構維持不變，為了避免上層P2P執行Rejoin動作，並減少了傳送維護P2P覆疊網路結構之reactive機制產生的Update訊息數量；同時，此機制在不建置SCTP協定下，且可達到類似SCTP使用多張網卡之效果。

With the vigorous development of various types of large-scale content delivery application services, P2P has become indispensable in today's Internet world. With the growing popularity of wireless network infrastructure, service support operations in these P2P streaming system must face a challenge. In this thesis a brief action node changing hands on the P2P overlay network structure, and instability problems caused for the P2P streaming system action node handoff proposed a hidden mobile node handoff mechanism, when the action node Changes in IP, the original P2P structure remains unchanged, at the same time in order to avoid the upper P2P execution the the Rejoin action, and to reduce the transmission maintenance P2P overlay network structure of the reactive mechanism Update number of messages;, this mechanism does not build the SCTP Agreement, and achieve similar to SCTP use multiple MACs that effect.
