Public safety networks are receiving more attention and priority in the several countries as the state authorities deal with unsuspected situations and natural disasters. Heterogeneous wireless networks with wireless devices supporting multitude of radio access technologies are witnessing increasing interest from public safety consumers. Energy efficiency in such networks has become an important design...
In this paper we propose a clustering mechanism for improved energy efficiency in aerial based access systems suitable for disaster recovery scenarios and large scale public events. The aerial base station is a low altitude platform (LAP) station that provides access to several terrestrial nodes on the ground over a prescribed coverage area. The terrestrial nodes are battery operated power constrained...
Cloud computing is currently emerging as the de facto standard for Internet service provisioning. This uptake is motivated, among other aspects, by the significant reduction in energy consumption that can be achieved by centralizing, consolidating and optimizing large IT infrastructures. At the same time, however, users expect to access cloud services via wireless access networks using smartphones...
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...
Aerial telecommunications networks based on Low Altitude Platforms (LAPs) are expected to optimally meet the urgent needs of emergency relief and recovery operations for tackling large scale natural disasters. The energy efficient operation of such networks is important given the fact that the entire network infrastructure including the battery operated ground terminals, exhibit requirements to operate...
Improving the energy efficiency of the ICT sector is becoming an ambitious challenge for industries and research communities alike. Understanding how the energy is consumed in each part of an ICT system becomes fundamental in order to minimize the overall energy consumed by the system itself. In this paper, we propose an experimentally-driven approach to (i) characterize typical wireless access network...
The continuous increase in the energy production cost, together with environmental sustainability issues, is leading research communities, governments and industries to focus their efforts on a reduction of the global CO2 footprint. Information and communication technologies, which represent the nervous system of the globalized economy and society, account for a significant percentage of the overall...
