Opportunistic Sensed Data Dissemination in Vehicular Environments

Description of research

Vehicular Sensor Networks (VSNs) are emerging as a new network paradigm for sensor information sharing in vehicular environments. In these networks, vehicles continuously disseminate location-relevant sensor data in order to generate an extended awareness with regard to, for instance, road conditions, traffic flows, and accidents. Examples of sensors are GPS, chemical spill detectors, still/video cameras, and vibration sensors, to name a few. In contrast with Wireless Sensor Networks (WSNs), vehicles have much higher power reserves and resources and therefore are not typically affected by energy or storage constraints. However, vehicular environments are highly mobile which leads to sudden variations in vehicle density and to intermittent connectivity. In addition, due to the high amount of data exchanged, the bandwidth available may exhaust easily if not carefully shared among participants.

The focus of this research is on the dissemination of sensed data to targets of interest (e.g., vehicles at specific geographical regions, roads, road-side units) while minimizing the amount of data inserted into the network. Our approach lies in discovering, assessing, and seizing opportunities for data exchange based on the available context information.
