Cellular Base Station Powered by Hybrid Energy Options

Energy Allocation Policy for Cellular Networks Powered by Renewable Energy

The explosive wireless data service requirement accompanied with carbon dioxide emission and consumption of traditional energy has put pressure on both industry and academia. Wireless networks powered with the uneven and intermittent generated renewable energy have been widely researched and lead to a new research paradigm called green communication. In this paper, we comprehensively consider t...

Dynamic Base Station Energy Saving with Relays

Energy Efficient Military Mobile Base Station Placement

This research deals with an energy efficient network for military mobile base station placement. The proposed method is based on minimizing the energy loss of military communication networks where the base station is moving along a preset path and the users are constantly moving in an independent speed and direction. It takes into account the free space loss and the knife edge effect for the en...

Managing Green Datacenters Powered by Hybrid Renewable Energy Systems

The rapidly growing server energy expenditure and the warning of climate change have forced the IT industry to look at datacenters powered by renewable energy. Existing proposals on this issue yield sub-optimal performance as they typically assume certain specific type of renewable energy sources and overlook the benefits of cross-source coordination. This paper takes the first step toward expl...

Characterizing Energy-Delay Tradeoff in Hyper-Cellular Networks with Base Station Sleeping Control

Base station (BS) sleeping operation is one of the effective ways to save energy consumption of cellular networks, but it may lead to longer delay to the customers. The fundamental question then arises: how much energy can be traded off by a tolerable delay? In this paper, we characterize the fundamental tradeoffs between total energy consumption and overall delay in a BS with sleep mode operat...
