Quality of Service Adaptation in wireless network

Emerging high-speed networks and powerful end-systems give rise to a new class of applications, such as video-on-demand and teleconferencing. Such applications are very demanding on Quality of Service (QoS) because of the isochronous nature of media.

  • To provide end-to-end QoS support.
  • To integrate network, transport and operating services.
  • To support the new emerging services with QoS guarantees.Qos is used to provide requested level of service to the users through the users interface .

    During QoS violations, QoS adaptation is done transparently, such that the transition takes place from one system to another system to provide requested level of service
