IEEE 802.16j增強IEEE 802.16的標準,透過Mutlihop的RS (Relay Station),可增加無線通訊的訊號涵蓋範圍(Coverage Extension),並且透過高覆蓋率增加網路系統中使用者的傳輸速度(Throughput Enhancement)。雖然RS佈建可帶來傳輸速率增加的好處,但如果沒有慎選RS佈建的位置將會導致傳輸效能變差。因此本論文探討在已知BS(Based Station)和SSs(Subscriber Stations)位置的情況下,自動選擇適當的RS佈建個數及位置,讓訊號涵蓋範圍和傳輸速度比起沒有使用RS轉傳的網路來的更好。本論文RS佈建的方式將同時考慮到固接式的用戶端(Fixed SS)及移動式的用戶端(Mobile SS)頻寬需求。透過實驗模擬,本文所提出的方法比隨機佈建RS的方式能達到顯著的效能改善。
IEEE 802.16j enhances the flexibility of IEEE 802.16e standard, by exploiting multihop transmission through relay station to increase the coverage area and increase transmission rate. Although the usage of relay station can improve system throughput, the deployment strategy may also determine the final system performance. The objective of this thesis is to propose a relay deployment strategy which can automatically determine a suitable number of relay stations and the suitable locations for relay deployment. To make the proposed strategy more practical, bandwidth requests from both fixed subscribers and mobile subscribers are take into considerations. Through simulation, the proposed relay deployment strategy has significantly performance improvements in comparison with random deployment strategy.
