Traffic-Aware Techniques to Reduce 3G/LTE Wireless Energy Consumption

The 3G/LTE wireless interface is a significant contributor to battery drain on mobile devices. A large portion of the energy is consumed by unnecessarily keeping the mobile device’s radio in its “Active” mode even when there is no traffic. This pproject aims to reduce this portion of energy consumption by learning the traffic patterns and predicting when a burst of traffic will start or end. We develop a technique to determine when to change the radio’s state to optimize energy efficiency.
