無線資料傳輸會受到通道衰減的影響，利用合作多樣性(cooperative diversity)為一種有效的解決方法。在無線隨意網路(wireless ad hoc network)中，能藉由節點間彼此分享天線來達到合作多樣性。因此，許多傳輸架構被提出來，但其中僅少許的演算法能提供服務品質保證(quality of service, QoS)。
本論文依據分時多重擷取(time division multiple access, TDMA)系統架構提出具服務品質保證的路由演算法。我們所提出的具服務品質保證路由演算法除了路徑的尋找，還分配分時多重擷取系統所使用的資料時槽、傳輸速率和傳輸功率給路徑上的所有連結。隨著路徑上資料的傳送，各節點可藉由接收多個路徑成員的傳送以達到合作多樣性，提高通訊品質以達到低end-to-end outage probability的目的。我們可以由模擬結果看出，本篇論文所提出的具服務品質保證路由演算法能有效提升系統效能。

Wireless transmission suffers from channel fading. An efficient solution is to utilize cooperative diversity. In wireless ad hoc networks, cooperative diversity can be achieved by sharing antennas between nodes, and for this reason, many transmission schemes has been proposed. However, rare of these transmission schemes can provide quality-of-service (QoS).
In this article, we propose a time division multiple access (TDMA)-based QoS routing protocol. For each data flow with QoS requirement, the proposed QoS routing protocol not only discovers a route, but allocates TDMA slot, transmission rate and transmission power for each link on this route. Nodes can obtain diversity by receiving multiple members’ transmissions. Since many parameters of the proposed QoS routing protocol can affect the system performance, we develop computer simulations to give a design overview.
