Although several works in the literature promise signigicant energy savings for wireless access infrastructures through energy-saving strategies, the number of implementations in real systems is limited, if not zero. This is mainly due to the lack of hardware and software support, especially for monitoring and controlling the wireless access devices. In this demo, we present an energy-saving framework...
Energy efficiency is acknowledged as a pivotal issue for a sustainable development of wireless networking technologies. Traditionally, most works in the area focused on the user equipment, where battery duration represents a key asset. However, as the smartphone and tablet revolution fuels a massive deployment of wireless networks, often in the form of WiFi hotspots, more and more attention is expected...
IEEE 802.11 WLANs are a very important technology to provide high speed wireless Internet access. Especially at airports, university campuses or in city centers, WLAN coverage is becoming ubiquitous leading to a deployment of hundreds or thousands of Access Points (AP). Managing and configuring such large WLAN deployments is a challenge. Current WLAN management protocols such as CAPWAP are hard to...
To be able to serve the traffic demand in today's mobile networks, more than 123.000 base stations (BSs) have been deployed by the different network providers in Germany. These BSs are working 24/7 and are dimensioned to serve capacity demand during busy hours. Currently no mechanisms for a load adaptive network reconfiguration are implemented. As a result, much energy is wasted during times in which...
