Paper Title:
Joint Routing and Spectrum Assignment Algorithm in Cognitive Radio Networks
  Abstract

Aiming to the shortcoming of traditional route protocols in cognitive radio networks, joint cognitive routing and spectrum assignment (JCRSA) algorithm was proposed. According to the characteristic of cognitive network, the most capacity channel is selected as communication channel on every link, and JCRSA calculates the transmission delay on every link for a given packet, and then uses classic Dijkstra algorithm to find the smallest transmission delay route. According to the route table, spectrum is assigned on every link. Simulation results show that the End-to-End delay of JCRSA is less than that of traditional routing algorithm.
