Energy efficient multi-player smartphone gaming using 3D spatial subdivisioning and PVS techniques

Abstract

With the advent of feature rich smartphone platforms such as Android and iOS, people can now enjoy a wide variety of applications on-the-go. Among these applications, games are one of the most desired types. However, as bigger screens, faster CPUs and interfaces supporting higher bandwidth (WiFi, 3G, LTE) consume more power, battery lifetime becomes a bottleneck on such devices. In this paper, we present novel techniques that combine 3D spatial subdivisioning, Potentially Visible Set (PVS) and Visual Perception based Localisation (VPL) methods to estimate the non-critical game states to save wireless interface energy with minimum processing penalty. Our techniques and algorithms are realised in a commercial game and can save up to 57% of wireless interface energy (which is, about 22.8% overall system energy) while retaining game play quality. © 2013 ACM.
