|Issue Date:||2003||Citation:||Wang, B.,Chua, K.C. (2003). Transmission control policy for data services over a time-varying wireless channel. IEEE International Conference on Networks, ICON : 617-621. ScholarBank@NUS Repository.||Abstract:||In this paper, we study the transmission control problem for data services over a time-varying wireless channel. A data user with general arrival statistics needs to decide from time to time whether or not to transmit a packet based on its buffer occupancy and observed channel state. Each decision incurs some rewards/costs representing different QoS aspects. Our objective is to find an optimal transmission policy (if it exists) that maximizes the expected average reward per unit time. We discuss the existence of a stationary optimal policy and its structural properties. Simulation results suggest that different balance points can be easily achieved by simply adjusting the reward parameters. ©2003 IEEE.||Source Title:||IEEE International Conference on Networks, ICON||URI:||http://scholarbank.nus.edu.sg/handle/10635/72076||ISBN:||0780377885||ISSN:||15566463|
