摘要

行動裝置近年成長速度相當的快，意味著行動同儕網路上的應用也跟著成長，而同時需要較大量運算資源的應用程式逐漸被開發，像是影像串流、雲端運算諸如此類等。這表示行動同儕網路(MP2P)將面臨更多的挑戰，原先存在的問題用既有方法已無法有效處理，例:拓樸落差、裝置差異性及服務品質(QOS)等。本論文中將處理上述問題，我們所提出的方法(Heterogeneity-Aware overlay Technique, HAT)專注在服務品質及裝置差異性上做處理，但同時考量到拓樸落差。實驗結果顯示利用HAT所建構的上層拓樸在服務品質上確實比前人所提的LTM及SBO方法好，這確保了用戶端在使用較耗資源的應用時能更有效且快速的執行，也證明此新的方式將更符合現在使用的需求。

Nowadays, most of the people have mobile devices with them. We install applications on those devices and utilize those services. With the improvements of those services, resource consumption has also grows. That means, The problems in MP2P encounter more challenges than ever before. Such as topology mismatching and heterogeneous property have to be take into consideration. Otherwise those problems will make resource consumption even worst. In this paper, we deal with the problems mention above. Our proposed method focus on the heterogeneous property. In the meanwhile, the topology mismatching problem was one of our concerns too. The simulation result shows that the overlay built with our method result in better QOS. Thus matches the needs of today's requirement. Such as video streaming, cloud computing and service that consume large resource.
