| dc.description.abstract | 無線網路的蓬勃發展使得無線的即時傳輸日益重要，例如無線的視訊會議需要穩定的傳輸品質，而以往routing的演算法並沒有提供一個良好的方法去解決保留頻寬的問題。這篇論文的目的是為了在mobile ad-hoc network(MANET)的網路環境中提供高效率的 quality-of-service routing (QoS routing)，每個行動裝置利用Time Division Multiple Access (TDMA)的方法。我們所提出的是On-Demand QoS Routing Protocol，每一個source要傳資料時才broadcast route request packet，在找路的同時計算每一條路徑平均的最小可用頻寬，在destination收到許多路徑後，從中選出平均頻寬最大的路徑，並沿著該路徑由destination回溯到source，分別對路徑上的每個link選擇適當的time slots。我們針對每個link可以使用的time slots，分別去計算該time slot對整體網路的影響力，並選擇影響最小的time slots保留起來，當成未來將要使用的time slots。 | zh_TW |
| dc.description.abstract | The QoS routing is an important issue in wireless mobile ad hoc networks. It is known that resource reservation is the best technique to guarantee QoS. Lots of the reservation-based QoS routing protocols have been proposed before. However, the effective bandwidth calculation problem and the bandwidth reservation problem have not been addressed seriously in the literature. Here, we proposed a bandwidth reservation QoS routing protocol for TDMA-based multihop ad hoc networks. We propose an algorithm to guide the destination to choose the route that is most likely to satisfy the QoS requirement and an algorithm to reserve the proper time slot and thus keeps more free time slots for future requests. Our protocol only requires the information of one-hop neighbors. Simulation results show that our protocol can achieve high route establishment probability and low packet loss rate with a reasonable cost. | en_US |
