Abstract

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, this approach leads to a polynomial time complexity gradient optimisation algorithm which seeks a judicious balance between the QoS experienced by the users and the overall energy consumption of the network.
