Information

Overview

• This model implements the communication system of the agent library as a partial model
• It is based on communication via UDP
• It is used by all implemented agents

Concept

The communication takes place via UDP network communication and is implemented with the help of elements from the DeviceDriver library. The inbox is refreshed based on a sample time, the outbox is triggered by an external boolean input.

Since sampling creates time events, the simulation performance will be bad for models with a high number of equations. For this reason, an alternative refresh mechanism can be used with "usePoke=true". In order to use this mechanism the component "MessageNotification" needs to be added to the system.

The partial agent implements the message parameters performative, sender, receiver, reply to, content, ontology and message ID. The parameters are described in the reference.
