Described is a technology in which Bluetooth.RTM. devices, e.g., navigation devices, are enhanced with additional power amplification to allow long range radio communication links between moving vehicles and/or between moving vehicles and roadside hubs. In one example, collection and dissemination of traffic information, including aggregation and filtering, is facilitated via a Bluetooth.RTM. vehicle-to-vehicle and/or vehicle-to-roadside hub ad-hoc network. Also described is efficient connection establishment and data transfer for vehicle to vehicle and vehicle-to-roadside hubs via the enhanced Bluetooth.RTM. radio. The ad-hoc network comprising a mesh of vehicles/a supernode also facilitates the exchange of information that originated at an Internet source.
