How can I add a "payload" to the packets when they are sent from the vehicle to the drone? The drone should read this payload and then broadcast a warning message to the other nodes. For example, if there is an accident.

is it possible to interface both MATLAB and SUMO with NetSim at the same time? Use SUMO for vehicle movement and MATLAB for drone movement with NetSim handling the network communication

The following is one approach you could explore:

1. Modify/Add Payload: To include the necessary information in the packet's payload, you'll need to make code modifications. After adding the payload, use Wireshark to verify that the payload has been successfully added and is being transmitted as intended.

2. Payload Processing on the Drone: That added payload can be read by the drone to consider whether to send a warning message or not using some kind of a conditional check 3. Warning Message Broadcast: If the drone determines, based on the payload, that a warning message needs to be broadcast to other nodes or vehicles, it can add this warning message to the payload of reply packets. Alternatively, a new application or communication protocol can be configured on the drone to send a warning message to the vehicle or other relevant nodes when the specified condition is met. This warning payload can be included in the communication between the drone and the vehicle.
