Energy consumption of large-scale networks has become a primary concern in a society increasingly dependent on information technology. Novel solutions that contribute to achieving energy savings in wired networks have been proposed to mitigate ongoing and alarming climate change and global warming. A detailed survey of relevant power-saving approaches in wired networks is presented here. We give a...
Energy optimization has become a crucial issue in the realm of ICT. This paper addresses the problem of energy consumption in a Metro Ethernet network. Ethernet technology deployments have been increasing tremendously because of their simplicity and low cost. However, much research remains to be conducted to address energy efficiency in Ethernet networks. In this paper, we propose a novel Energy Aware...
Energy saving is a really interesting topic in today's networks. Indeed, Information and Communication Technologies (ICT) systems are energy greedy, they require more and more energy and as energy is more and more expensive, thus we seek to save it. Accordingly, energy saving has recently received considerable attention as a promising approach for delivering ICT services with environmentally conscious...
Quality of service (QoS) is still a crucial issue that deals with the IEEE 802.16 network performance. Scheduling is a key component of the MAC IEEE 802.16 layer which ensures QoS for different service classes. In this paper, we give a detailed simulation study for some scheduling algorithms by evaluating their performance in order to support the QoS classes. We propose a new WiMAX scheduling algorithm...
