“…However, a PSN provides only communication for public services related to the police, firefighter, and medical assistance. Lambert et al [12] investigate the network's performance offered to the user when only a limited part of the network infrastructure is available, but it does not consider the possibility of using drones to provide service to the uncovered users. The approaches proposed in [13][14][15] are similar to ours.…”

Today's wireless communication networks are very reliable. However, in case of a disaster, these networks can be overwhelmed by a tremendous amount of requests which they can not cope with. We propose a deployment tool for UAV (unmanned aerial vehicle)-aided emergency networks for such disaster scenarios. By using UAVs, femtocell base stations will be brought to and hovered at their assigned location. We applied this deployment tool on a realistic disaster scenario in the city center of Ghent, Belgium. The results are very promising although a large amount of drones (> 1000 type 1 or > 370 type 2 drones) is required to provide full coverage for 1 h. Halving the user coverage results in 1.8 to 2 times less drones. More effectively is to increase the drone's fly height. A 10-m higher fly height can result in a reduction up to 13%. However, above 100 m, the influence is not significant any more. Decreasing the user's service level has no significant influence on the number of required drones for the considered scenario. Furthermore, a prediction model for the number of required drones based on the intervention duration and the user coverage is proposed.

“…Traditionally, most of the energy we use today comes from fossil fuels. Oil (petroleum), coal, and natural gas made up 82 percent of the world's primary energy supply in 2012, and 68 percent of electricity was generated by burning fossil fuels [1]. However, using fossil fuels has some drawbacks.…”

“…Manuscript received before 2030, leading to a global fuel shortage and a steep increase in oil prices [1]. Whether this depletion will indeed occur is a contested point in literature, but even adversaries of this theory agree that political instability in oil-producing countries can result in severe oil price shocks, with devasting effects for fossil fuel-based economies.…”

Traditionally we highly rely on fossil fuels for our energy provisioning, but there are drawbacks on using these fossil fuels: the risk for depletion in the future; the increased in cost as already observed during the last few years, and the high impact on the climate change. One virtually carbon-neutral alternative to fossil fuels are renewable energy sources, like solar energy. In this paper, we investigate the energy and network performance of a wireless access network powered by the traditional electricity grid and a PV (PhotoVoltaic) panel system. An energy-aware management system for the future wireless access networks is proposed. This system consists of the management of the energy provisioning and storage system and the application of the proposed energy-saving strategies which aim to reduce the energy footprint through the traditional grid in case a renewable energy shortage occurs. To evaluate the network's performance, this paper proposes a deployment tool with the above described energy-aware management system. The results show that it is promising to further investigate a more evolved and complex energyaware management system.

Abstract:Because of the increase of the data traffic demand, wireless access networks, through which users access telecommunication services, have expanded, in terms of size and of capability and, consequently, in terms of power consumption. Therefore, costs to buy the necessary power for the supply of base stations of those networks is becoming very high, impacting the communication cost. In this study, strategies to reduce the amount of money spent for the purchase of the energy consumed by the base stations are proposed for a network powered by solar panels, energy batteries and the power grid. First, the variability of the energy prices is exploited. It provides a cost reduction of up to 30%, when energy is bought in advance. If a part of the base stations is deactivated when the energy price is higher than a given threshold, a compromise between the energy cost and the user coverage drop is needed. In the simulated scenario, the necessary energy cost can be reduced by more than 40%, preserving the user coverage by greater than 94%. Second, the network is introduced to the energy market: it buys and sells energy from/to the traditional power grid. Finally, costs are reduced by the reduction of power consumption of the network, achieved by using microcell base stations. In the considered scenario, up to a 31% cost reduction is obtained, without the deterioration of the quality of service, but a huge Capex expenditure is required.
