一個應用於行動隨意網路上可變傳輸速率之服務品質保證路由協定

在行動隨意網路上提供服務品質保證是一個十分熱門且具有挑戰性的研究主題，而其中，如何設計一個具有服務品質保證的路由協定更是扮演了重要的角色。可變傳輸速率則是無線網路傳輸上的特性，隨著使用頻道的品質好壞，資料的傳送可以不同的速率進行。就我們所知，目前所有提出來應用於行動隨意網路上的服務品質保證路由協定都是以單一傳輸速率為基礎。在本篇論文中，我們提出一個將服務品質保證與可變傳輸速率兩者結合的路由協定，目標在於滿足服務品質保證的同時，利用可變傳輸速率的特性將其效能提升。透過模擬，我們發現相較於單一傳輸速率，可變傳輸速率之服務品質保證路由協定的確可以獲致較好的表現。

Providing Quality of Service (QoS) in mobile ad hoc networks is a very popular and challenging research topic, and how to design a QoS routing protocol plays an important role. Multi-rate capability is a feature for wireless transmission with which data can be transmitted at different rates according to the channel quality. To the best of our knowledge, all of the proposed QoS routing protocols for mobile ad hoc networks are based on single-rate transmission. In this thesis, we propose a multi-rate QoS routing protocol, which aims to provide QoS support with multi-rate enhancement. Through simulations, we show that incorporating multi-rate capability into QoS routing protocol can achieve better performance than that of single-rate.
