A Location-Routing Problem in Designing Optical Internet Access with WDM Systems

A Location-Routing Problem in Designing Optical Internet Access with WDM Systems In this paper, we deal with a location-routing problem in designing the optical Internet with WDM systems. This problem arises from the design of broadband local access networks that deliver high-speed access service to residential subscribers. The problem is to find an optimal location of the gateway and optimal routing of traffic demands in the optical access network. We develop mixed-integer programming models for solving the location-routing problem to minimize the total cost of network elements used in the network while carrying the offered traffic. By exploiting the inherent structure of the problem, we derive two effective tabu search procedures. We present promising computational results of the proposed solution procedures. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Photonic Network Communications Springer Journals

Abstract

In this paper, we deal with a location-routing problem in designing the optical Internet with WDM systems. This problem arises from the design of broadband local access networks that deliver high-speed access service to residential subscribers. The problem is to find an optimal location of the gateway and optimal routing of traffic demands in the optical access network. We develop mixed-integer programming models for solving the location-routing problem to minimize the total cost of network elements used in the network while carrying the offered traffic. By exploiting the inherent structure of the problem, we derive two effective tabu search procedures. We present promising computational results of the proposed solution procedures.
