Abstract

This paper presents an application of Artificial Bee Colony (ABC) algorithm for survivable optical network design. The dedicated path protection (DPP) survivability scheme is modelled by ABC algorithm for establishing two link-disjoint paths between each node pair in demand matrix considering single link failure scenarios. In the proposed algorithm every food source represents a lightpath between each node pair in optical network and the position of food sources are modified by artificial bees to minimize the total number of utilized wavelengths by working and spare lightpaths. Simulation results demonstrate that the proposed ABC based survivability scheme is able and efficient to design fault-tolerant optical transport networks.
