Profile Based Topology Control and Routing in Wireless Optical Networks

Abstract

The problem of topology control and routing of bandwidth-guaranteed flows over wireless optical backbone networks is addressed. The input is a potential topology and a traffic profile. The constraints are that of limited interfaces at each node and the limited link bandwidth, and the objective is to maximize the throughput. The problem turns out to be NP-Hard.

A new framework for integrated topology control and routing is proposed. A simple heuristic is proposed, and efficient rollout algorithms are proposed which enhance the heuristic. The routing problem is formulated as a multi-commodity flow problem, and is used to enhance the rollout algorithms to achieve a higher throughput.

Another set of heuristics is proposed which use matching theory and multi-commodity flow formulation of routing to achieve the desired results. We enhance the heuristics to provide fairness to the ingress-egress pairs in terms of how much traffic we route for each of them.
