Analysis of the energy conservation aspects of a mobile context broker

Abstract

Mobile devices are increasingly becoming the main mean of interaction for inhabitants of ubiquitous computing environments. Pervasiveness of these devices as users' personal gadgets and their high-tech capabilities allow capturing of broad contextual information about the physical environment, users social profile and preferences. These modern roles of mobile devices facilitate a number of user and environment related context consuming and producing applications to be hosted on these devices. But without a coordinating component on the mobile device these context consumers and providers are a potential burden on device resources, specifically the effect of uncoordinated computation and communication shortens the battery life. In this paper we briefly describe the concept of a Mobile Context Broker and focus on the energy conservation benefits gained through the context coordination facilities provided by the Mobile Context Broker executing on a smart mobile device. The reported results signify reduction in energy consumption. © Springer-Verlag Berlin Heidelberg 2011.
