在NCTUns平台上模擬WiMAX點對多點網路

Abstract

IEEE 802.16 (WiMAX) 是目前最重要的新興無線技術之一，係由Intel、Nokia等國際大廠所共同制定推動的通訊標準。它被預期將成為下一代網路無線的主流，提供家庭、公司、及各種通訊所需的服務。IEEE 802.16規格定義了PMP與Mesh兩種運作模式。PMP模式主要的運用在”最後一哩”的傳輸，用來取代傳統的固接式網路，如xDSL與T1；Mesh模式則屬於網路的基礎建設，提供高速可靠的骨幹網路。

IEEE 802.16-2001 是最初訂定的 802.16 標準，到現在發展的時間已經超過六年了。然而卻沒有一個公開的網路模擬器能提供 802.16 網路的模擬。我們的目標在NCTUns這個模擬平台上開發屬於 802.16d 的模組。根據我們的成果，希望可以幫助研究者更方便快速地完成他們的研究。

The IEEE 802.16 (WiMAX) standard, supported by several major companies such as Intel and Nokia, is one of the most important standards for broadband wireless access technologies in the future. It is expected to become the mainstream of network technology for home user, business, and telecommunication in the future. The standard defines two operation modes – PMP (Point-to-MultiPoint) and Mesh. The PMP mode aims to replace traditional wired last-mile access network, such as xDSL and T1, with a novel wireless access technology. The Mesh mode was designed for construct infrastructure network supporting high-speed reliable backbone networks.

The first IEEE 802.16-2001 standard was developed from 2001. The IEEE 802.16 standard family has been developed over six years. However, so far there is not a generic network simulator for simulating such networks. Our work is based on the NCTUns network simulator to develop a protocol suite of WiMAX network simulator in accordance with the IEEE 802.16d Standard. Based on our work, researchers can easily analyze what they research and save more experiment time.
