The emerging high-rate Wireless Personal Area Network (WPAN) technology is capable of supporting high-speed and high-quality real-time multimedia applications. In particular, video streams are deemed to be a dominant traffic type, and require Quality of Service (QoS) support. However, in the current IEEE 802.15.3 standard for MAC (Media Access Control) of high-rate WPANs, the implementation details of some key issues such as scheduling and QoS provisioning have not been addressed. In this paper, the authors first propose a Markov Decision Process (MDP) model for optimal scheduling for video flows in high-rate WPANs.
