Controlling Multimedia QoS in the Future Home Network Using the PSQA Metric [PDF]

The Computer Journal, 2006
Home networks are becoming ubiquitous, especially since the advent of wireless technologies such as IEEE 802.11. Coupled with this, there is an increase in the number of broadband-connected homes, and many new services are being deployed by broadband providers, such as TV and VoIP. The home network is thus becoming the 'media hub' of the house.
