Aiming at the problem that the consistency between load capacity and the actual traffic volume, the road grade analysis in urban traffic network. Propose the improved GROCC algorithm based on the traditional Dijkstra algorithm. It is a global path planning method based on real-time traffic information. In this algorithm, the parameter, the number of recommended times are used as an important factor...
We investigate the problem of gradual migration from fixed grid to flexible grid in optical networks by designing heuristics to selectively upgrade WSSs on ROADMs. We evaluate the performance of our scheme under different traffic profiles.
A cost-effective capacity planning method of WDM networks is proposed for increase of traffic load. An improved cost-based ant colony algorithm is presented from pheromone increase and update mechanisms to solve the planning problem. Simulation results show the applicability of our planning method.
