DS-Cinema: Distributed P2P Seat Reservation System

DS-Cinema is a distributed peer-to-peer system for cinema seat reservation. There is no central server managing the application logic or storing data: everything is distributed across the nodes in the network. The goal of the project is to implement from scratch the distributed coordination algorithms studied in class. In particular, I used the Ricart-Agrawala algorithm together with Lamport Clocks to guarantee mutual exclusion: if two users click at the same instant, they won’t have problems, but one of them will get the seat as booked, while for the other it will appear as occupied. The system also handles failures: if a node crashes during a reservation, the others detect it via timeouts and continue to work normally. New nodes can dynamically join the network and synchronize with the current state.
