摘要
与传统的无线多跳网络不同,多radio无线mesh网络的路由器是固定的,节点具有异构性。提出一种协作的异构多radio无线mesh系统路由设计模型,该路由协议模型按路由发现过程,分4个子模块,分别为半同步式邻居发现机制r、adio异构刻画的路由metric、分层的信息发布模型、满足业务需求的路由算法。该路由协议模型对多radio的异构性进行了刻画,采用分层协作方式共享网络拓扑信息。实验证明这种适应异构无线环境的跨层路由设计方案比传统方案更符合用户需求。
Compared with traditional wireless multi-hop networks, the multi-radio wireless mesh network router is fixed and the nodes diverse. A novel collaborative routing design model of heterogeneous multi-radio wireless mesh systems was proposed. This model includes four sub-models a half-synchronized neighbor discovery mechanism, a routing metric with characterized radio, a layered information distribution system, and a reasonable routing algorithm The model multi-radio diversity and employed layered collaboration to share topological information. The results indicate that this cross-layer routing of a heterogeneous wireless environment could be more convenient to use than traditional approaches.
