I've been working on omnet++ veins to simulate a highway scenario and the relationship between vehicle and RSU(roadside unit).I'm trying to figure out how to dynamically change the bitrate of my RSU setting
*.**.nic.mac1609_4.bitrate = 6Mbps
Above is the original setting of bitrate,I'm hoping to adjust this value based on the distance between RSU and vehicle.Are there any module I can use to get the distance and furthermore respectively manipulate the bitrate between different vehicle nodes and RSU nodes
In Veins 4.7.1, you can set the modulation and coding scheme (MCS), so - by extension - the bitrate, via a call to the setMCS method of the MAC layer. Calculating the distance is supported via a method of the Coord class which is used to represent node positions.
