| dc.description.abstract | 無線網狀網路提供企業與個人一個容易擴充和配置的網際網路存取
方案。進一步藉由多頻道與多天線的技術，無線網狀網路將可支援更
高的網路流量，以滿足現今越來越高的頻寬需求量。許多研究專注於
IEEE 802.11無線網狀網路的頻道分配與路由機制，探討此無線網路
可達到的頻寬增益與網路效能在理論上的限制。然而，IEEE 802.11
在資料傳輸頻寬與傳輸距離的限制下，並不適用於都會型的無線網狀
網路架構。本篇論文即針對下一代的無線寬頻last-mile網路連結：
IEEE 802.16無線都會型網路，提出一個適合IEEE 802.16無線都會型
網狀網路的速率調適頻道分配與路由演算機制。論文中將IEEE
802.16的TDMA特性納入考量。模擬結果顯示，所提出的速率調適頻道
分配機制與現今IEEE 802.11直接移植的方法比較，不但在頻道的使
用數量上較少，而且具有較高的頻道利用率。而在三個路由演算法的
比較上，提出的速率調適隨機多重路徑演算法善加利用了IEEE
802.16多重調變的性質，達到了整體上較高的網路吞吐量。 | zh_TW |
| dc.description.abstract | Wireless mesh networks provide an easy deployed and extensi-
ble solution to access Internet or communicate with each other for both
enterprises and individuals. With the help of multi-channel and multi-
radio, wireless mesh network can support more tra¢ c load to meet
higher and higher bandwidth requirement in this modern time. There
have been researches that focus on channel assignment and routing al-
gorithm for IEEE 802.11 multi-channel environment to achieve better
network throughout. However, the data rate and transmission range
of 802.11 is limited and is not suitable for a large area metropolitan
mesh network deployment. This thesis presents a rate-adaption chan-
nel assignment and routing algorithm for IEEE 802.16 multi-channel
multi-radio network in mesh mode which is expected as the last-mile
wireless broadband connectivity. We takes 802.16 TDMA characteris-
tic and modulation/rate adaption into consideration. The Simulation
results show that our channel assignment procedure uses fewer chan-
nels and better channel utilization than the migrated 802.11 greedy
approach. Among the three comparing routing protocols, our protocol
performs better in multi-rate 802.16 mesh network and results in higher
aggregate throughput. | en_US |
