%X <p>A green grooming algorithm, called as time-aware green grooming (TAGG) algorithm, is proposed for scheduled traffic requests. By comparing the transmission energy consumption for different traffic grooming strategies, the most energy-efficient traffic grooming strategy is selected in TAGG algorithm for traffic requests. Moreover, in order to further reduce the transmission energy consumption, a scheme is put forward to trigger the operation of merging light-paths. According to the moment of tearing down light-paths, the scheme can determine the moment of merging light-paths for traffic requests, which can reduce the number of required router ports and transceivers, and improve the wavelength bandwidth utilization. Simulation shows that the proposed TAGG algorithm can reduce transmission energy consumption effectively.</p>
