The authors introduce a novel system to monitor traffic using deployed nodes placed uniformly on the highway to monitor the road traffic. They take advantage of the Cat eye's on the road by adding sensing capability (metal detectors) with embedded processors, the sensing feature provides an accurate detection of the average number of vehicles and its average speed on the highway using an aggregation function. The main goal of the proposed system is to monitor the traffic flow on the highways and to provide drivers with safety notifications messages. In their system, they calculate the size of clustering and communication timing between nodes.
