“…As part of a network, the base station is capable of switching off in some periods. Other actions can also be taken, such as offloading users to hot spots or delaying them, a concept known as delay-tolerant users (DTU) [35].…”

“…For example, delay-tolerant users would allow the operators to manage their network in a more energyefficient manner. Users are aware upfront of possible upcoming delays and express their willingness to wait for their requests to be processed [35]. This concept specifically shows advantages in the case where network operators need to reply to Smart Gird requests for providing ancillary services and adjusting energy load [24].…”

International audiencePowering cellular base stations with renewable energy are one of the long-term strategies for achieving green networks and reducing their operational costs. As an energy provider, the power grid is evolving into a smarter one, which allows more energy-efficient cellular networks and enables cooperation and interaction with the smart grid. On one hand, cellular networks can use harvested renewable energy and on-site energy storage to reduce their energy costs. On the other hand, the price of electricity depends on the energy load, which will eventually contribute to decreasing the peak consumption and global energy cost. In this paper, we propose new integration architecture for renewable energy-powered cellular networks and the smart grid. The proposed architecture is designed based on the classification and the analysis of the existing proposals and the requirements of the smart grid, renewable energy systems, and cellular networks

The network reconfiguration (NR) techniques are key strategies to reduce the energy consumption in cellular networks. In this paper we propose a mechanism to further increase the energy gains resulting of the application of these strategies. Our approach exploits the delay tolerance of the users to increase the periods when no reconfiguration is needed. We developed the analytical model of the mechanism dynamics and we evaluated it numerically for two NR strategies. The results show up to 13 percentage points of performance improvement regarding the traditional NR strategies for a maximal delay of 50s.

International audienceNowadays, smartphones are used to download files such as movies, music, etc. These files present some flexibility in delivery time; we exploit this feature to reduce network overload peaks. If the network is overloaded, downloads are postponed, thus reducing the traffic load during rush hours. We propose an architecture that enables the network to determine the best time to trigger a download that is queued. This architecture is based on a specific server in the network and a mobile application. This contribution describes the proposed architecture, presents the developments that have been made, and analyzes the performance of this novel concept
