In the past few years, Ethernet Passive Optical Networks (EPONs) have rapidly gained large popularity in broadband access networks. However the current standard has no management protocols aiming at reducing power consumption. In this paper, we propose an Energy Management Mechanism (EMM) within the IEEE 802.3ah control scheme. The main idea is to switch Optical Network Units (ONUs) to sleep mode...
We consider the problem of joint rate scheduling and lossy data compression in a two-way relay network with distortion-sensitive stochastic packet traffic. A relay node facilitates exchanging packets between the two sources. Network coding at the relay improves energy efficiency at the expense of additional packet delay. In addition, network coding couples the source queues through the distortion...
Energy efficiency is of critical importance in future wireless communication systems where networked low-power devices relying on batteries should be able to communicate transparently. We present a novel cross-layer energy-adaptive scheduling and queue management framework EAED (Energy Aware Early Detection) for minimizing energy consumption in WLAN mesh networks. EAED aims at saving energy by delaying...
