of the Dissertation Roam: A Scalable Replication System for Mobile and Distributed Computing by David Howard Ratner Doctor of Philosophy in Computer Science University of California, Los Angeles, 1998 Professor Gerald J. Popek, Co-chair Professor W. W. Chu, Co-chair Mobile computing is rapidly becoming a way of life. Users carry their laptops, PDAs, and other portable devices with them almost constantly, whether their mobility takes them across town or across the world. Recent hardware innovations and improvements in chip technology have made mobile computing truly feasible. Unfortunately, unlike the hardware industry, much of today's system software is not "mobile-ready." Such is the case with the replication service. Nomadic users require replication to store copies of critical data on their mobile machines, since disconnected or poorly connected machines must rely primarily on local resources. However, the existing replication services are designed for stationary environments, a...
