Bandwidth Provisioning with QoS User Utility Function in NUM

This paper primarily addresses the design of user utility function for network utility maximization (NUM) problems. The general approach of current existing user utility models is designed to reflect network´s ability to meet the minimum bandwidth requirement. In contrast, user satisfaction is also often influenced by user experience with the quality of service (QoS), the cost to attain the service, and functional of the product. With this new perspective, we show a new insight of how user makes decision on transmission rate.
