Admission control in wired networks has been traditionally used as a way to control traffic congestion and guarantee quality of service. Here, we propose an admission control mechanism which aims to keep the power consumption at the lowest possible level by restricting the more energy-demanding users. This work relies on the fact that power consumption of(More)
We formulate the problem of joint energy and quality of service (QoS) optimisation in packet networks and show how it can be formalised using the control capabilities inherent in G-network theory, which also includes the overhead due to control traffic. Using known energy consumption characteristics of network routers and of network link driver equipment,(More)
Energy saving in networks has traditionally focussed on reducing battery consumption through smart wireless network design. Recently, researchers have turned their attention to the energy cost and carbon emissions of the backbone network that both fixed and mobile communications depend on, proposing primarily mechanisms that turn equipments OFF or put them(More)
Overprovisioning and redundancy has contributed towards better survivability and performance in networks, but has led to inefficient use of energy. Proposals for energy aware networks of the near future aim to reduce the energy consumption by switching off or putting to sleep individual network devices. Here we propose a mechanism that is taking this(More)
