N2  - The popularity of home networking technologies has been considerably increased in recent years. However, media distribution is still not ready to satisfy users' quality expectations in wireless home networks. Due to bandwidth variations and high error rates, a number of Quality of Service (QoS) mechanisms have to be deployed in the network in order to guarantee a certain level of quality. In this work, we study a user-centric QoS management approach aimed at providing QoS services primarily satisfying user requirements rather than traffic constraints. Unlike traditional QoS approaches that always give multimedia applications pre-determined high priority due to their strict latency and loss requirements, the proposed approach classifies traffic according to user preferences, thereby ensuring a certain quality regardless of the application requirements. The QoS network configuration is performed according to user profiles and automatically updated in case of changes in the network or user environment. Apart from the proposed architecture including system components, communication interfaces and QoS policy-based management, we enhanced the system with an admission control approach aimed at flexible regulating of traffic load on the network. The implementation details and experimental results demonstrate practical applications and advantages of the proposed approaches in wireless home networks.
