We want to reduce the carbon footprint of the existing/upcoming communication networks. This includes designing greener cellular networks that save significant amount of energy by switching off less loaded base stations. We have been working on state-of-the-art energy efficient resource allocation techniques for cellular networks that achieve various trade-offs between energy, coverage, and throughput. We are highly interested in optimizing the device sleep cycle for improved energy savings and user experience.

Historical and future climates are simulated by setting up a suite of initial conditions and seeing how these conditions change when various factors, called forcings, are applied. For example, how does Earth’s surface temperature change if it receives more or less heat from the Sun? . We could win valuable time if solar activity declines and slows the pace of global warming a little.
