Abstract

A wide range of emerging multimedia services (e.g. IP telephony, video conferencing, video-on-demand) require Quality of Services (QoS) guarantees in both wired and wireless networks. Adaptive QoS provisioning and control are especially necessary to meet the QoS requirements in dynamic heterogeneous multi-hop wireless networks. This paper proposed an adaptative mechanism to achieve better perceptive and quantitative QoS for real-time multimedia services suitable for such networks. The mechanism is built based on the theoretical analysis of the end-to-end delay bounds and the necessary and sufficient conditions to maintain the data flow continuity of real-time connections.
