the following topology using a python script with Mininet: • You don’t need to know about the controller c0 now, just create using its own API. • You must use the Mid-Level APIs to create the given topology. • Use the CLI object to open the CLI of Mininet • Run the nodes and show the result.

In this programming assignment, you will implement the above ROS smart mobility system in city. create a service that the ROS service client node will send the GPS location of the autonomous vehicle. Consequently, the ROS service server will send back the current weather status by using c/c++

JAVA You are requested to implement a “message buffer and response connector” class using Javaprogramming language. The following figure depicts a message buffer and response connectorclass, followed by detailed operations specifications. The message buffer and response connectorclass has three operations, send(), receive(), and reply().Your program should create two separate threads for testing your implementation, a producerthread, and a consumer thread. The producer thread sends a message having a structure (string,integer) – e.g., (add, 3) or (multiply, 7) - to a consumer thread via a message buffer and responseconnector. The consumer thread encapsulates a SimpleCalculation class that has two operations,add() and “multiply(). You should implement the SimpleCalculation class as well. When theconsumer thread receives a message from the connector, it extracts the message and then callsone of the operations on the SimpleCalculation class, depending on the message. For example,the…
