Adgt.js: A web application framework for peer-to-peer location-based services

Abstract

Mobile applications are increasingly taking advantage of user geographic location to provide sophisticated Location-Based Services (LBSs). Unfortunately, most LBSs rely upon centralized infrastructures, with serious problems as regards user privacy. For this reason, the research community has proposed a number of decentralized protocols and studied their effectiveness and efficiency by means of simulations. In this paper, we describe Adgt.js, a truly cross-platform, WebRTC-based implementation of the ADGT georeferenced peer-to-peer overlay scheme. Moreover, we present a concrete LBS example, realized with Adgt.js, to illustrate how simple and powerful such a framework is.
