Clustering techniques for traffic grooming in optical WDM mesh networks

In this paper, we are:trying to study the traffic grooming problem by minimizing. overall network cost that includes the transceivers required as well as the number of wavelengths A mathematical formulation of the traffic grooming problem In mesh networks Is proposed. We also describe a heuristic using Blocking Island (BI) paradigm. Simulations have been carried out to prove effectiveness of our heuristic
