Design of tele-commanding system using asynchronous message service based on delay tolerant network for space communication

In this paper, we propose a tele-commanding system model based on delay tolerant network (DTN) for the space communication. For designing this model, we use asynchronous message service (AMS) which is one of application services of DTN. We propose the tele-commanding algorithm, which allows AMS messages to be recognized as a tele-commands. This enables nodes received a tele-command message to conduct the mission according to tele-command. The performance of the proposed service model is evaluated in the implemented testbed, and the result shows that it is available in the space network to control remote nodes with the model.
