無線通訊技術的快速發展,近年來許多公共場域都已經架設無線網狀網路提供給大眾上網服務。無線網狀網路擁有多重跳躍的無線傳輸特性,可以輕易擴充網路服務範圍。因此,對於網路架設,相對容易許多。無線網狀網路對外部網路的資料傳輸(上傳),是必須透過網狀閘道器才能傳送出去。在這樣的情況下,我們發現無線網狀網路中,離網狀閘道器越遠的網狀路由器其效能越差,導致整體資料傳輸的不公平性。所以我們在本篇論文將提出一個新的傳輸機制,稱為「無線軟體定義網狀網路之拓樸感知公平上傳機制」。我們透過軟體定義網路來收集整個無線網狀網路的網路拓樸,然後根據網狀路由器和網狀閘道器的跳躍數、分支度多寡,來給予不同的傳輸速率和傳輸時間。最後,我們再搭配虛擬代幣和交換器信譽機制,來達到傳送支付公平性。在最後模擬的結果,我們可以看到,我們的方法在資料上傳時,的確可以提供比較佳的傳送支付公平性。
With the rapid development of wireless communication technology, in recent years, many public places have set up wireless mesh networks (WMN) to provide Internet access services for people. The wireless mesh network has the characteristics of multi-hop wireless transmission, which can easily expand the network service range. Therefore, it is relatively easy to set up a network. The data transmission (i.e., uplink data) of the wireless mesh network to the external network must be transmitted through the mesh gateway (MG). In such a case, we found that in a wireless mesh network, the farther away the mesh router (MR) is from the mesh gateway, the less effective it is, resulting in unfairness in the overall data transmission. Therefore, we will propose a new transmission mechanism in this paper, called “Topology-Aware Fairness Uplink Transmission Mechanism in Wireless SDN-Based Mesh Networks”. We use software-defined network (SDN) architecture to collect the network topology of the entire wireless mesh network, and then assign different transmission rates and transmission times according to the number of hops and degrees of the mesh router and mesh gateway. Finally, we combine virtual tokens (VT) and exchange reputation mechanisms to achieve fairness. In the final simulation results, we can see that our method can indeed provide better transmission payment fairness when uploading data.
