abstract
Distributed Sensor Hub is a fully decentralized peer-to-peer platform for smart-city sensor data collection and replication, designed to operate across multiple nodes without any central coordinator. Each node may manage connections to multiple local sensors, ingest their readings through a pluggable sensor interface to support different sensor types, and maintain a local replica of the shared system state. The platform disseminates sensor updates through push-pull gossip and resolves conflicts with deterministic timestamp-based Last-Writer-Wins merging, providing eventual consistency across replicas. To remain operational in realistic distributed environments, the system combines gossip-based membership, phi-accrual failure detection, and antientropy recovery after crashes or temporary network partitions. In CAP terms, the project prioritizes availability and partition tolerance over strong consistency, while still guaranteeing convergence once communication is restored.
