Briefly describe each step in the design of a CAN communication network for a car that consists of a central unit (ECU) and four monitoring systems.

Question: Design a communication network for a small building consisting of three rooms by using at least two different technologies to send two messages from room-1 to room-3 using different technology for each message. These messages must not interfere with the communication of room-2 which is using the same communication technologies (Hint: adopt the concept of collision avoidance protocol). The available technologies are Bluetooth, CAN and GSM.

Briefly describe each step in the design of a CAN communication network for a car that consists of a central unit (ECU) and four monitoring systems (fuel, brake, heating, engine). Use your "P" number as ECU input identifier and assign different and unique identifier to each monitoring system. Use filter and mask to differentiate messages from ECU to monitoring system and from monitoring systems to ECU.
