Communication network architectures, systems and methods for supporting a network of mobile nodes. As a non-limiting example, various aspects of this disclosure provide communication network architectures, systems, and methods for supporting a dynamically configurable communication network comprising a complex array of both static and moving communication nodes (e.g., the Internet of moving things). In particular, methods and systems for in-vehicle sensing using a captive portal that collects sensor data samples from sensor devices in electronic devices of end-users.
