Verteilung von Public-Sensing-Aufgaben basierend auf Android

Abstract

Within recent years, mobile phones have become carriers of numerous smart applications and the potential of these mobile devices is even greater than it might look at first glance. Behind the combined pieces of information that many mobile devices possess lies hidden meta information that accounts for more than the mere sum of its parts, e.g. beginning and end of a traffic jam. Using our framework, researchers and scientists can create versatile requests for information and send them to mobile clients within a couple of minutes. For instance, environmental data could be sensed periodically without any user intervention. Prototype models of several information requests have been created to demonstrate the various aspects of possible public sensing scenarios, bearing in mind the users' concerns regarding data security and privacy. Our framework does not only manage creating and sending of specifically designed tasks, it also dispatches their executions on the client side, sends back the response, and interprets it. Therefore developers can fully concentrate on the content of sensing information.
