Implementation of the MAC Layer of a DSRC identification system
Descrição
DSRC (Dedicated Short Range Communications) is a well known widespread technology.One of the main applications of DSRC is RTTT (RoadTransport and Traffic Telematics), especially EFC(Electronic Fee Collection) on tolled roads, bridges or tunnels.Other vehicle-related applications had been envisaged, suchas car parking or fuel refilling automatic payment. Theseapplications were successfully developed, deployed and are in current use in Portugal. Especially for EFC, medium accesscontrol is of utmost importance. In this paper it is presentedan implementation scheme for the MAC-layer of the RSE(road side equipment), suitable for low-cost microcontrollers,to operate between the two equipments (as in Figure 1), andalso the MAC layer of the SPI connection, of the twoMicrocontrollers present within the RSE. The result is interface software that controls the referred communication, embracing hardware and software into a join solution. This hardware works with both transfer rates, the LDR (Low Data Rate), the current technology and the MDR (Medium Data Rate).
