Abstract

This work deals with the problem of synchronizing multiple distributed databases over a broadcast network, such as satellite networks. The proposed method is based on introducing network coding techniques besides extending the well-known database reconciliation algorithm, the (CPISync). One key element is to elect a master node that manages the operations in a central manner. Performance is shown in terms of completion time for full synchronization, and average number of packets exchange. Compared to point-to-point and traditional broadcasting synchronization methods, the algorithm implementing network coding allows reaching the lower-bound for the number of packets exchange.
