無線隨意網路下多重頻道媒體存取協定之探討

Abstract

在無線隨意網路中，媒體存取協定通常只利用單一頻道，使得系統效能無法大幅增加。如果利用多重頻道，讓同一時間可傳輸的節點配對增加，將可提高系統的傳輸效能。目前已經有許多有關於多重頻道媒體存取協定設計的研究，在這篇論文中，我們將這些研究作一個完整的分類整理，並將設計的流程圖勾勒出來。針對每個部分，我們深入探討與比較目前現有的解法，並指出每種作法可能存在的優缺點。

In wireless ad hoc networks, system performances can not be largely raised when using a medium access control (MAC) protocol that is based on a single-channel model. If multiple channels are available, system throughput can be increased by enabling more concurrent transmission pairs. So far, there are many papers concerning about the design of multi-channel MAC protocols. In this paper, we do a comprehensive survey on this work. We look insight each part of the whole design flow and make comparisons on the existing solutions.
