Using Coordination Middleware for Location-Aware Computing: A Lime Case Study

Abstract. The decoupling between behavior and communication fostered by coordination becomes of paramount importance in mobile computing. In this scenario, however, coordination technology is typically used to deal only with the application data necessary to orchestrate the process activities. In this paper, we argue instead that the very same coordination abstractions can be used effectively to deal also with information coming from the physical context—a fundamental aspect of mobile computing applications. We cast our considerations in Lime, a coordination model and middleware designed for mobile computing. To support our arguments with concrete examples, we report about the development of Tuling, a proofof-concept application enabling the tracking of mobile users. The lessons learned during development enable us to assess the feasibility of the approach and identify new research opportunities.
