abstract = "An extended pathfinding routing and wavelength assignment (RWA) algorithm based on ant colony optimization (ACO-EP) is proposed in order to enhance the global exploratory capability. The algorithm introduces heuristic function which is based on wavelength availability to solve the problem of unbalanced wavelength usage and introduces volatilization coefficient and random interference mechanism based on traffic intensity to improve the shortcoming of easily falling into local optimum. The communication success rate and transmission delay performance are simulated in the scene of Iridium satellite constellation. The results show that when traffic intensity is 138.6Erl, compared with the original ant colony algorithm, ACO-EP algorithm can improve the communication success rate by 23.56% and reduce the communication delay by 13.89%.",
