| dc.description.abstract | 近年來Wi-Fi 無線網路的技術發展成熟，並有許多相關的部署應用。相對於Wi-Fi而言，WiMax是一種新穎的技術，WiMax比Wi-Fi具有更高頻寬容量、傳輸範圍更廣、傳輸速度更快等優點…。而在WiMax部署運用成熟前兩者將會共存運作。在無線網路中，頻寬是很珍貴的資源，因此為了提供使用者更多元及更佳的服務品質(QOS)，有效率的頻寬管理演算法是必需的。
在本文中將結合Wi-Fi與WiMax相關技術，提供一個能依照網路狀況動態調整頻寬資源的演算法。本文最大的貢獻在於我們所提出的方法能解決在無線網路中互相矛盾的爭議-頻寬的使用率、新連線的阻絕率、換手連線的中斷率。我們的方法相當靈活，能真實反映網路實際狀況，提供一個適當的資源使用平衡點，讓網路能達到最佳的效能。 | zh_TW |
| dc.description.abstract | Recently, Wi-Fi systems have been widely deployed for public mobile Internet services. Contrast to Wi-Fi,WiMax is a novel technology. WiMax have a lot of advantages than Wi-Fi, including high capacity、large communication range and high speed etc…. WiMax and Wi-Fi will coexist before WiMax construction and development are ripe . Bandwidth is an extremely valuable and scarce resource in a wireless network.Therefore,efficient bandwidth management is necessary in order to provide high quality service to users with different requirements in a multimedia wireless/mobile network. In this paper, we combine Wi-Fi and WiMax technolog, propose an dynamic bandwidth management algorithm that adjusts bandwidth capacity adaptively based on existing network conditions.
The most important contribution of our work is an adaptive
algorithm that is able to resolve conflicting performance criteria- bandwidth utilization, call dropping and call blocking
probabilities. Our algorithm is quite flexible, is responsive to
current traffic conditions in cellular networks, and tries to
strike the appropriate performance balance between contradictory requirements for QoS sensitive multimedia services. | en_US |
