Calculation of Necessary QoS for User Satisfaction with a QoS Mapping Matrix

This paper studies a method for getting necessary QoS for user satisfaction. For a service, its user satisfaction can have some aspects and must be treated from every aspect. However, it is not easy to find feasible QoS that satisfies a user from every aspect. This paper assumes QoS mapping with the multiple linear regression and defines a QoS mapping matrix. By popular matrix operations, which include generalized inverse, we can decide necessary QoS for required user satisfaction in every aspect. To confirm the effectiveness of the method, this paper shows the numerical results.
