自西元1998年,802.16無線網路被提出之後,在無線網路的領域世界中無疑是投入了一顆震撼彈。近年來,由於無線網路的蓬勃發展,從802.11的無線網路到目前即將要應用到實際生活的802.16 無線網路,帶領著人們進入另外的無線網路新世界。人們不必再侷限於有線網路,可以透過無線網路縮短了人與人之間的距離並進而實現地球村的夢想,這是對網路使用者所帶來的好處。在都市中的佈線成本方面也可以比過去的有線網路縮減許多,這是其對網路公司帶來的實質效益。另外由於802.16無線網路的傳輸距離可以達到30哩,這對各國的偏遠區域如:山區或者是沙漠等,均可以解決因為地形關係所造成的有線佈建問題以及可以使這些區域的人民享有更好的醫療、資訊品質。在802.16的架構中,由一個基地台(Base Station ,簡稱BS)和一個至數個用戶台(Subscribe Station,簡稱SS),中間採用無線通訊,並標榜著兩者傳輸距離可以達到30哩,每個SS底下連接一個子網路(例如:802.11無線網路)。由於在802.16無線網路中,當使用者因為移動而跨出其所連接的節點時,就要執行所謂的換手程序,這時候就會產生了換手延遲時間,在這段時間內由於連線中斷的關係,所以傳送往使用者先前連接節點的資料封包會全部遺失無法收到。因此我們在參考802.11無線網路中的移動管理機制:以多點傳送為基底(Multicast-based)以及預測機制之後,我們針對802.16因為換手延遲時間所造成的資料封包遺失問題提出解決辦法。這篇論文提出了一套採用Multicast-based機制再加上預測機制並考量使用的時間點來使得封包遺失數量下降。在未來將可以繼續將此機制作延伸的研究,將其應用到服務品質保證上,Quality of Service(QoS)。
The Announcement of 802.16 has given people the new experience of wireless networking. Using wireless network distance between people can be shortened and the realization of global village can be achieved. Deployment of 802.16 in urban area can benefit the network company in term of reducing the wire deployment cost. With transmission range over 30 miles, 802.16 can provide telecommunication for country with less developed infrastructure and area that is hard to deploy wire line such as mountain or dessert. In the 802.16 architecture, we have a Base Station (BS) and several Subscriber Stations (SS). The communication between BS and SS is connected by wireless media. Each subnet (for example: 802.11) is connected under a SS. In 802.16 network environment, mobile host will execute handoff procedure when mobile host moves from old network to new network. Packet lost and handoff delay will occur during handoff process. We use the mobility management scheme introduced for 802.11 wireless networks such as multicast-based and predictive mechanisms to reduce packet lost during handoff in 802.16 wireless networks. In this paper, we propose a new mechanism based on multicast-based, predictive mechanism and using time point as consideration to reduce packet lost. In the future, we hope that we can extend this research by including Quality of Service (QoS).
