Hello, I have a research project for which I need to use SUMO and its APIs. I will describe the scenario of what I am trying to do.
I am trying to simulate the emergency charge scheduling of multiple electric vehicles via a drone or a mobile charging device. The drone reports to a Global Charging Station (reports means taking instructions to go and charge, reporting termination of operation in case of failure to charge or even if the drone itself needs to be charged). When N number of vehicles request different units of charge from the drone, the drone compiles the requests and based on different algorithms, prepares a priority list of charge requesting vehicles. The drone then flies from its docking station and charges all the vehicles (the vehicles are all inside the drone's charging radius) according to the priority list. I need to output the total flying distance of the drone. What I have done so far is, I have generated the net, route and trip files for the vehicles, but I don't know how to declare a drone in SUMO. I also don't understand how to make a flying path for the drone, since the vehicle's at the moment are moving from one edge to the other in a 10x10 Manhattan Grid. I need to know if I can simulate a drone in SUMO and declare its path. If so, then how? I also need to understand how the priority algorithms can be used in the python script where I am using SUMO and TracI. Please let me know if you have any questions.
