Enhanced ACO based RWA on WDM optical networks using requests accumulation and re-sorting method

Abstract

A novel idea to enhance the ACO method for solving the problem of RWA in WDM optical networks has been proposed in this paper. This enhancement has been achieved by suggesting the idea of re-sorting the requests that are needed to be connected in order of their distances to the destinations before serving them. The enhanced ACO version has been tested through this paper on both static and dynamic RWA types with different wavelength conversion scenarios. Results clearly show the feasibility of our enhanced ACO algorithm.
