“…In [9] the authors have proposed a bitrate control scheme based on congestion feedback over the Internet. In [25][26][27] authors have presented adaptation based on network state and congestion control over UMTS transport channels. Authors in [28] have presented an adaptive bandwidth allocation scheme based on the queue length and the packet loss probability.…”

Quality of experience (QoE) driven adaptation scheme for voice/video over IP

Network quality of service (NQoS) of IP networks is unpredictable and impacts the quality of networked multimedia services. Adaptive voice and video schemes are therefore vital for the provision of voice over IP (VoIP) services for optimised quality of experience (QoE). Traditional adaptation schemes based on NQoS do not take perceived quality into consideration even though the user is the best judge of quality. Additionally, uncertainties inherent in NQoS parameter measurements make the design of adaptation schemes difficult and their performance suboptimal. This paper presents a QoE-driven adaptation scheme for voice and video over IP to solve the optimisation problem to provide optimal QoE for networked voice and video applications. The adaptive VoIP architecture was implemented and tested both in NS2 and in an Open IMS Core network to allow extensive simulation and test-bed evaluation. Results show that the scheme was optimally responsive to available network bandwidth and congestion for both voice and video and optimised delivered QoE for different network conditions, and is friendly to TCP traffic.

“…The use of filter is essential for the operation of the mechanism in order to avoid wrong estimations of the network conditions. Similar to the Decision Feedback Scheme [7], we define an upper bound for the bandwidth that a streaming application, which coexists with any other application in the same channel, can reserve from the available bandwidth of the transport channel. This condition restricts the video transmission to use no more than a% of the maximum available bandwidth of the transport channel.…”

UMTS is evolving toward a future wireless all-IP network. In this paper we present how it supports realtime IP multimedia services, as these services are expected to drive the adoption of wireless all-IP networks. The scheme of real time streaming video is one of the newcomers in wireless data communication and in particular in UMTS, raising a number of novel requirements in both telecommunication and data communication systems. This scheme applies when the mobile user is experiencing real time video content. In this work we focus on the design and implementation of a rate and loss control mechanism for monitoring the UMTS network state and estimating the appropriate rate of the streaming video data.
