Abstract: Based on DSDV protocol, an approach of cross-layer routing design is proposed. A reasonable length and the smallest probability of re-routing has been chosen and tested. This is a quality link mechanism which can be applied to Wireless Mesh Networks(WMN) based on IEEE802.11x. It does not require amendments of the existing MAC layer and can be added to the existing protocol as a separate module. This paper uses the cross-layer routing design to choose the routing in multi-hop networks, which can save the system expenditure and optimize system’s integrated performance.

摘要： 在DSDV协议的基础上，提出一种跨层路由设计的方法，选择一条具有合理长度和最小重传概率的路由进行测试。该链路质量机制可应用到基于IEEE802.11x的无线Mesh网络中，无须对现有的MAC层进行修改，即可作为一个单独模块加入到现有协议。在多跳网络中使用该跨层方案进行路由选择，能节省系统开销，优化系统的整体性能。
