Utility-Based Resource Allocation for Soft QoS Traffic in Wireless Networks

This paper studies the utility-maximization resource allocation problem for soft QoS traffic in wireless networks, which demands certain amount of bandwidth for normal operation but allows some flexibility. With deviations to the known approaches and solutions, we propose a novel utility optimization model, which bounds the bandwidth allocation of each flow around its desired value and allows certain flexibility. We theoretically analyse this model and give a complete procedure to obtain the solution.
