摘要
尽管IEEE802.11x等协议作了很多优化处理以对物理层提供支持,但现有无线Mesh网络的性能仍然需要依赖于良好的路由协议进行正确的路径选择.路由判据是决定路由协议性能的关键因素之一.从路由判据的特点与构成,分析了路由判据设计相关问题,并从路由判据构成的四个主要研究方向(基本判据、干扰相关判据、负载相关判据和混合判据),对国内外相关研究进展进行了分析对比,指出了路由判据设计的发展方向.
Despite efforts to improve the current IEEE 802. 11 standard to fully optimize the physical layer, the performance of wire- less mesh networks still depends on the routing process for a correct selection of routes. Routing metric is a key factor of routing pro-tocol. Issues about the design of routing metric,based its feature and components, is analyzed. From the four main research perspec-fives (basic metric, interference-aware, load-aware and mix metric) of RM's components, correlational studies are introduced and analysed comparatively. The future direction of RM design is also indicated.
