A MQTT-based guide and notification service system

In recent years, the concept of Internet of Vehicles (IoV) is becoming a hot research issue. However, too much and clutter information received by drivers through IoV may affect their driving attention. It is necessary to provide drivers effective guide and notification services according to time, locations and events. This study proposes a Message Queue Telemetry Transport (MQTT) based guide and notification service system to provide information to the drivers. We establish a hierarchical and geographic grid architecture which provides location-based services. We also collect information from the vehicles, road and environment to calculate the weight of roads.
