| Abstract: | Due to the scarcity and imperfection of cognitive radio software simulation platform,this paper analyzes a simulation platform in depth,and proposes a dynamic routing algorithm for spectrum allocation based on cross-layer design,aiming to solve the deficiency of the Breadth-First Search（BFS） algorithm applied by the platform.In conclusion,through a series of simulations carried out by the updated simulation platform which adopts the new routing algorithm,it makes a better improvement in the accessing,transmission power and end-to-end throughput of the cognitive user. |
