Abstract

A method in one embodiment comprises: obtaining, by a first cloud-based IoT gateway service, a radio signal from a first mobile sensor device; converting the radio signal to a message in a machine-to-machine IoT connectivity protocol; and providing the message to a message broker that determines a topic of the message and publishes the message using the topic. The message is distributed to one or more additional mobile sensor devices using a content delivery network. The first mobile sensor device optionally obtains the radio signal from one or more additional mobile sensor devices by means of vehicle-to-vehicle communications. The radio signal comprises, for example, a distress signal of a given mobile sensor device and a K-Nearest Neighbor process is optionally used to identify other mobile devices in proximity to the given mobile sensor device.
