An integrated bandwidth allocation for energy saving in fixed-mobile networks

Minimizing the use of transceivers is an effective approach for achieving minimum energy consumption in convergent access networks. Synchronizing downstream transmissions can minimize the use of transceivers and reduce the number of switches of these components, to incur less consumed energy. In this paper, we propose the synchronization of downstream traffic to reduce the energy consumed in a fixed-mobile access network. Specifically, we present a novel synchronized integrated downstream bandwidth allocation scheme for saving energy. EPON is considered for the fixed part of the network and wireless technologies for integration are WiMAX, LTE and LTE_Advanced. The simulation results verify the proposed model and highlight the advantages of our scheme.
