End-to-End Rate Control in Communication Networks Considering User-Level Satisfactions

In this paper, we consider a rate control problem in communication networks based on the network utility maximization framework. To accurately model the satisfaction of a user to its service, we propose a new concept of the utility function, which is called a user-level utility junction, considering both transmitting and receiving sessions of a user together. We then formulate an optimization problem for rate control with user-level utility functions and develop a distributed rate control algorithm.
