The authors address the issue of how to reduce energy consumption of the wireless interface during multiplayer gaming sessions on mobile devices. Reducing energy consumed by the wireless interface is achieved by putting it in a low-energy state when it is not used. They leverage the dead reckoning technique used in existing games. In dead reckoning, future locations of objects in a game are estimated based on their current locations and velocities. The difference between the extrapolated and true locations is known as the dead reckoning error. They propose an algorithm that employs the dead reckoning error rate to dynamically control the state of the wireless interface.
