ABSTRACT
This chapter discusses the wireless resource allocation problem in the downlink of a wireless network with a central control system, such as a cellular base station. It examines to maximize the total utility of all users. The chapter considers two common types of traffic: hard quality of service (QoS) traffic and best-effort traffic. Three allocation algorithms of these two types of traffic are, the Hard QoS allocation for hard QoS traffic, the elastic allocation for best-effort traffic, and the mixed allocation for the coexistence of both types of traffic. The chapter provides a number of key theorems as the general design guidelines for utility-based resource allocation in wireless networks. It explains the performance of the proposed schemes is validated via simulations. The chapter describes that optimal wireless resource allocation needs to account for the traffic demand, total available resource, and wireless channel quality, rather than solely be dependent on channel quality or traffic type as assumed in most existing work.
