Atenuação dos efeitos da temperatura ambiente em redes OCDMA 2-D utilizando controle de potência baseado em algoritmo de enxame de vaga-lumes

This paper presents an approach for power control in OCDMA 2-D (Time/Wavelength) networks taking in account the adverse effects of environmental temperature variation in optical fibers. The proposed system uses a meta-heuristic based on behavior of firefly swarms to optimize the allocated power for each user in the network. The network structure and the optimization algorithm, as well the computational simulations are implemented in MATLAB® environment. The obtained results are analyzed based on variation in code parameters and show that the algorithm is efficient to realize the power control in OCDMA networks.
