The postal communication form and the message-oriented communications within Interplanetary Networks (IPNs) and Deep-Space Communication Networks (DSCNs) leads to converting the communication process to a pure s ignaling process executed through exchanging messages between the communication parties. Based on that, the definition of the term “ Service ” takes a new dimension, namely, the interaction ef ficiency and effectivity achieved under these conditions. Therefore, it is m ore efficient to describe the service quality based on the interaction quality of related communi cation session(s). In that respect, the QoS model used in terrestrial communication networks will not be sufficient for describing message-oriented and time-delayed communication networks. Therefore, we introduce the Quality of Interaction (QoI) concept as an alternat ive model to QoS as well as a basic model for describing the efficiency and effectivity of co mmunications in IPNs and DSCNs. For this purpose, the message-oriented communication characteristics are firstly addressed and accordingly the QoI model is developed, where low-l evel and high-level QoI are suggested. This paper deals with the low level QoI and discuss es the main parameters required to estimate the QoI of a communication process. Moreover, the proposed QoI concept can also be used as a basis for resource management in future IPNs and DSCNs. Finally, although QoI is designed for high-delay communication networks like IPNs and DSCNs; nevertheless, it can also be used as a basis for improving the ne tworking efficiency in conventional networks and terrestrial Internet.
