An optimization framework for traffic restoration in optical wireless networks with partial link failures

Next, the paper describes how the generic optimization model can be used for the FSO networks. The specific features of the failures observed in such networks (FSO is highly sensitive to atmospheric conditions) imply the necessity of treating the dimensioning problem in its chance constrained programming version which is NP-hard by its very nature. For that we have developed an iterative heuristic scheme that makes use of the exact solution method developed for the generic case. Numerical results illustrating the so-obtained robust solutions of the dimensioning problem are also reported.
