1. Breathe to Stay Cool: Adjusting Cell Sizes to Reduce Energy Consumption: Adapt cell coverage (and even big others bigger and turn off some) according to network load to make cellular networks more energy efficient. Interesting, this seems to align well with work going on at Ericsson and probably others.

2. Reducing energy consumption in IPTV networks by selective pre-joining of channels: How to safe energy in IPTV networks, but results are not really promising. But a very nice talk, as always from Jon Crowcroft.

3. Energy Proportionality of an Enterprise Network: Build power models for your network infrastructure and use SNMP to measure the current configurations and operation modes (traffic rates etc.) to estimate the overall power consumption. Use this information to optimize your network.
