路由是认知无线电网络（CRN）中最重要和最基本的问题之一。在本文中，我们提出了一种有效的路由方案。我们的主要贡献有三方面。首先，我们提出了一个包含功率控制的频谱感知半结构路由（SSR）框架。通过采用转发区和路由区，SSR可以有效利用本地实时频谱动态，同时保证全局路由性能。其次，考虑到 CRN 中缺乏路由协议性能分析模型 [1]，我们分析了 SSR 引起的延迟和可扩展性的上限。最后，提供了大量的仿真结果来验证 SSR 的性能。
Routing is one of the most important and fundamental issues in Cognitive Radio Networks (CRNs). In this paper, we propose an effective routing scheme. Our main contributions are threefold. First, we propose a spectrum-aware Semi-Structure Routing (SSR) framework which incorporates power control. By employing forwarding zones and routing zones, SSR can effectively utilize the local real-time spectrum dynamics and meanwhile guarantee the global routing performance. Second, considering the lack of analytical models for routing protocol performance [1] in CRNs, we analyze the upper bound of the induced latency and scalability of SSR. Finally, extensive simulation results are presented to validate the performance of SSR.
