市场上有许多商用无线网状网络 (WMN) 产品，但由于每个供应商实现 WMN 的方法不同且专有，因此存在不兼容性问题。这引发了对按照802.11s标准草案实现WMN的嵌入式解决方案的研究。在此实现中，它允许遗留系统在第二通道的帮助下连接到WMN，而不管平台如何。除此之外，多通道实现还用于在两个不重叠的通道之间分配负载。 2个信道分别用于传统站点连接到WMN和WMN骨干连接。本文旨在解释如何构建 Free BSD 的嵌入式版本以用作带有 PC 引擎 Alix 3d2 的无线网状路由器以及所完成的配置的详细信息。使用 Free BSD 8.2 操作系统 (OS) 的 WMN 实现，并在嵌入式系统上进行系统评估。
There are many commercial wireless mesh networks(WMN) products available in the market but incompatibility issues exist as the method to achieve WMN for each vendor is different and proprietary. This has led to the research of the embedded solution that implements the WMN in accordance with the 802.11s draft standard. In this implementation, it allows the legacy system to connect to the WMN regardless of the platform with the help of the second channel. Besides that, the multi-channel implementation is also used to distribute the load between the 2 non-overlapping channels. The 2 channels are used for the legacy stations to connect to the WMN and the WMN backbone connection respectively. This paper was written as an explanation on how to build the embedded version of Free BSD to work as a wireless mesh router with PC Engines Alix 3d2 and the details of the configurations done. The WMN implementation of the Free BSD 8.2 operating system (OS) was used and system evaluations were done on the embedded systems.
