Nomadic users require replication to store copies of critical data on their mobile machines. Existing replication services do not provide all classes of mobile users with the capabilities they require, which include: the ability for direct synchronization between any two replicas, support for large numbers of replicas, and detailed control over what files reside on their local (mobile) replica. Existing peer-topeer solutions would enable direct communication, but suffers from dramatic scaling problems in the number of replicas, limiting the number of overall users and impacting performance. Roam is a replication system designed to satisfy the requirements of the mobile user. Roam is based on the Ward Model, replication architecture for mobile environments. Using the Ward Model and new distributed algorithms, Roam provides a scalable replication solution for the mobile user. We describe the motivation, design, and implementation of Roam and report its performance. Replication is extremely important in mobile environments because nomadic users require local copies of important data.

As India is a densely populated country, any development project leads to the displacement of lakhs of people. Displacement is not just the physical relocation of displaced people but is also associated with social and economic consequences that disrupt the lives of people. The insecurities resulting from the same are manifold. They include human insecurity, social insecurity, economic insecurity, food insecurity, health insecurity, and gender-based insecurity. This paper briefly analyses the situation of displacement in India and reflects on the insecurities faced by the people displaced due to development projects.
