Enhancing UPnP Quality of Service by Intelligent Access Point

With the process of wireless local area networks (WLANs), the concept of digital home gradually plays an important role nowadays. For this reason, a standard called UPnP, one of the future trends, is proposed. UPnP provides many important functions, for example, active detection, zero-configuration, etc. The problems about the distribution of total bandwidth and QoS become more complicated since multiple services (e.g., Ftp, Streaming, VoIP) activate simultaneously. Under the architecture of UPnP QoS, we enhance and apply it to Intelligent Access Point (IAP) to redefine a new UPnP QoS architecture in our paper, and combine our UPnP QoS algorithm to proceed predation and distribution algorithm about the total bandwidth. In this paper, the IAP and users are permitted to do active detection and can adjust actively to get a better QoS. Finally, our simulation results reveal that the total bandwidth can be used in a more efficient way which means that out proposed scheme can always service more new coming users.
