A Quantitative Evaluation Method of Satellite Network Control Protocol based on Multi-attribute Utility Theory

Satellite network control protocol plays an important part in satellite communication system. Different design schemes of protocol have very different protocol attribute values. It is difficult to select a proper protocol solution from many solution alternatives with quite different protocol attributes, especially some mutual conflicted protocol attributes. Thereupon, this paper provides a multi-attribute utility theory based quantitative method to evaluate these protocol design schemes, in order to make a wise decision on how to select protocol solution. This method introduces several critical protocol attributes by utilizing a Petri net model, and aggregates them into a decision making matrix. On the basis of multi-attribute utility theory, quantitative evaluation values are achieved with the support of user attribute preference weight vectors. In the end, the paper presents experiments and discussions.
