Provided is a DCSS-OCR opportunistic cognitive routing protocol optimization method. First, a global optimization scheme is proposed for the expected link access opportunity and average transmission delay measure in a DCSS-OCR opportunistic cognitive routing protocol in order to achieve the optimal routing quality and stability of a heterogeneous cognitive network. Then, the correctness of the link access opportunity and average transmission delay expressions is verified through Monte Carlo experimental simulation and theoretical numerical analysis. Finally, the influence of main user activityon the routing link and path access opportunity and average transmission delay is simulated and numerically analyzed through joint optimization of multidimensional parameters. 种DCSS-OCR机会认知路由协议优化方法，首先，对DCSS-OCR机会认知路由协议中关于期望链路接入机会和平均传输延迟度量提出了全局优化方案，以实现异构认知网络最优的路由质量和稳定性。其次，通过Monte Carlo实验仿真和理论数值分析验证了链路接入机会和平均传输延迟表达式的正确性。最后，通过多维度参数联合优化设置，仿真和数值分析了主用户活动对路由链路和路径接入机会、以及平均传输延迟的影响。
