近年來無線寬頻網路各項技術不斷的被提出與討論。其中IEEE 802.16j為目前受到高度關注的無線通訊標準，增訂了多躍式中繼網路架構。藉由中繼站(Relay Station，RS)的建置與運作，取代建置大量基地台(Base Station，BS)耗費的高昂成本，並且延伸無線通訊的涵蓋範圍及提升網路傳輸流量，因此中繼站須建置在何處才能達到增加網路的效能，變成為一個非常重要探討的議題。本論文針對在現存的IEEE 802.16網路，提出一個中繼站的佈建機制，在一個BS 所能覆蓋的範圍內，依據每個子區域不同傳輸流量的需求與現有分配的頻寬下，找出需佈建RS的子區域，並找出RS最佳佈建位置，藉以提升網路整體效率。根據實驗結果顯示，本論文所提出之機制能找出合適的RS佈建位置，並有效地提升網路傳輸效能。 In recent years many wireless broadband networking technologies were brought up and discussed. IEEE 802.16j is one of the most impressive one with its MMR network structure. Through the mechanism of Relay Station, high-cost base station could be substituted to give a broader network coverage and bigger bandwidth. Therefore the choice of location of these relay stations has become a topic that is worth discussing. This dissertation will start from the present IEEE 802.16 network, to figure out a relay station placement mechanism. Inside the acceptable range of the base station, find the best and most efficient sub-area for relay station by considering the differences in data flow and attributed bandwidth. The findings of this research will be verified through a series of experiments, and to finally conclude with the most suitable rule for the placement of relay stations
