  • Title: Comparison of Monte Carlo ray-tracing and photon-tracing methods for calculation of the impulse response on indoor wireless optical channels.
    Author: González O, Rodríguez S, Pérez-Jiménez R, Mendoza BR, Ayala A.
    Journal: Opt Express; 2011 Jan 31; 19(3):1997-2005. PubMed ID: 21369016.
    Abstract:
    We present a comparison between the modified Monte Carlo algorithm (MMCA) and a recently proposed ray-tracing algorithm named as photon-tracing algorithm. Both methods are compared exhaustively according to error analysis and computational costs. We show that the new photon-tracing method offers a solution with a slightly greater error but requiring from considerable less computing time. Moreover, from a practical point of view, the solutions obtained with both algorithms are approximately equivalent, demonstrating the goodness of the new photon-tracing method.
