Many algorithms for providing proportional delay differentiation and proportional loss differentiation have been proposed under wired networks. However, these algorithms suffer from low performance at encountering some distinct characteristics, such as location-dependent and time-varying channel capacity, which exist in wireless networks. This paper proposes a novel algorithm, Wireless Proportional Delay and Loss differentiation (WPDL) including a capacity-aware scheduler and a debt-aware dropper, to provide the proportional delay differentiation and proportional loss differentiation in a wireless network with a multi-state link. WPDL considers the channel state and debt information in order to improve the performance of scheduling and dropping. From simulation results, WPDL actually achieves proportional delay differentiation, proportional loss differentiation, lower queueing delay and loss, and higher throughput, compared with other methods in the wireless environment. © 2008 Springer Berlin Heidelberg.
