Abstract:

At least one of a set of topics published by one or more vehicle-located mobile gateways is subscribed to. A set of publication topics is created based on the first set of topics, the publication topics made available to a client. A subscription request is received from the client corresponding to a selected topic of the set of publication topics. First sequential data is received from the one or more mobile gateways in response to the subscription to the at least one of the set of topics of the one or more mobile gateways. Second sequential data is sent to the client responsive to the subscription request, the second sequential data being based on the first sequential data.
