Jiafu Wan, Di Li, Caifeng Zou, Keliang Zhou · 2012
Machine to machine (M2M) communications will lead to dramatic changes in the applications and services offered to citizens, allowing smart city to become a reality. In this article, we first introduce the new tendency in M2M development and analyze the construction frame of application systems in smart city. Then, an event-based architecture depending on SOFIA project is built to allow the management and cooperation among M2M components by mean of event manager. Based on this architecture, we conduct a case study in a vehicular context. M2M network architecture is introduced for vehicular networks. Finally, an event processing flow of vehicle maintenance services is designed to manage the mission-critical wireless messages.
