Challenges in Ubiquitous Data Management
Ubiquitous computing is a compelling vision for the future that is moving closer to realization at an accelerating pace. The combination of global wireless and wired connectivity along with increasingly small and powerful devices enables a wide array of new applications that will change the nature of computing. Beyond new devices and communications mechanisms, however, the key technology that is required to make ubiquitous computing a reality is data management. In this short paper, I attempt to identify and organize the key aspects of ubiquitous computing applications and environments from a data management perspective and outline the data management challenges that they engender. Finally, I describe two on-going projects: Data Recharging and Telegraph, that are addressing some of these issues.
