ABSTRACT: \ More vehicles are equipped with sensors that could collect massive data of wide-area environments. To leverage such data and protect clients' privacy, we naturally think of Federated Learning (FL) which trains a high-quality shared model through training decentralized data over clients and sending back only the model updates. However, a bottleneck might occur over the central server with a large amount of clients. This limitation motivates the need for decentralized FL where clients share their model updates with their neighbors instead of the central coordinator. We present a new decentralized FL algorithm with convergence guarantees to address two challenges: a) clients do not have static data but dynamically changing data; b) the connectivity graph is changing over time (e.g., nearby vehicles are not fixed). Finally, we develop a new decentralized FL simulator that provides a realistic modeling for the dynamic graph.
