Nowadays mobile multimedia applications are foundamental services brought to people by Universal Mobile Telecommunication System (UMTS). Multimedia services represent an ongoing challenge for every mobile operator. Nevertheless, a good business strategy involves a high Quality of Service (QoS) concerning data services, as well as optimal classic voice services. This work proposes an optimal scheduling algorithm to improve QoS of the video streaming service on UMTS network. We consider a statistical approach to avoid client buffer overflow and underflow resulting from the external user actions. The algorithm is particularly suitable for real-time interactive multimedia transmission of VBR streams. It takes into account the feedback of the real available buffer size periodically coming from client terminals. The aim of the algorithm is the minimization of losses due to user interaction.

Abstract
Nowadays mobile multimedia applications are foundamental services brought to people by Universal Mobile Telecommunication System (UMTS). Multimedia services represent an ongoing challenge for every mobile operator. Nevertheless, a good business strategy involves a high Quality of Service (QoS) concerning data services, as well as optimal classic voice services. This work proposes an optimal scheduling algorithm to improve QoS of the video streaming service on UMTS network. We consider a statistical approach to avoid client buffer overflow and underflow resulting from the external user actions. The algorithm is particularly suitable for real-time interactive multimedia transmission of VBR streams. It takes into account the feedback of the real available buffer size periodically coming from client terminals. The aim of the algorithm is the minimization of losses due to user interaction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
