The focus of EEWMI is towards the advancement of the current state-of-the-art in energy-efficient communication in wireless mesh infrastructure. The overall goal can be achieved by realizing individual goals, each one of which addresses a particular challenge towards optimizing energy. The individual goals are summarized below:

• The first goal is to find analytical models that describe the correlation between transmission power and positioning of access points w.r.t. energy consumption. In current setting it is not clear, whether putting access points in sleep mode while, e.g., increasing the transmission power of the remaining nodes will result in energy saving.
• The second goal is to optimize the energy consumption in wireless mesh networks by managing the number of active powered-on resources.
• Another objective is to construct energy-efficient communication protocols (routing and protocols) in a way that the availability of certain network services does not assume the permanent accessibility of all virtual or physical entities. This enables devices to change into an energy-efficient mode for certain time periods. Protocols have to support the synchronization of communication, the delegation of services, on-demand mechanisms, and an energy-efficient signalling.
• Finally, w.r.t. the Future Internet we discuss whether the methods developed for improving energy efficiency of WMIs might also be applied in principle in the Internet’s core network.
