Matrix Board Communication¶
The Matrix Board Communication DDS Demonstrator shows the application of the DDS protocol in a dynamic environment. Each board should publish the traffic it senses. Each matrix board should dynamically find the two closest upstream matrix boards and subscribe to them so it receives the traffic values they sense. According, to these two numbers the board should calculate the speed limit it will display. The traffic sensors are just random number generators that have some lower and upper bound. Similarly, the displayed speed limit starts from the maximum initial limit and decrements or increments in discrete steps while never going above the maximum.
Implementation¶
The Matrix Board Communication currently has the following implementations. Note that in some languages there are multiple proof of concepts in order to show that the dynamic aspect can be implemented in various ways.
