Multi-Objective Optimization Techniques in Topology Control of Free Space Optical Networks

To mitigate the effects of obscuration and attenuation, Free Space Optical (FSO) wireless networks employ topology control to dynamically reconfigure node connectivity based on changes in link state. Previous research in topology control has focused primarily on creating heuristics for computing optimal topology either in the physical layer (minimize bit error rate) or in the network layer (minimize congestion). This research presents a multi-objective optimization formulation of the topology control problem where by physical network cost and network layer congestion are jointly minimized.
