Adaptive streaming on heterogeneous networks

Abstract

Specific network protocols, like MobileIP, offer seamless connectivity to mobile systems. However, the QoS requirements of streaming applications and video conferencing systems require an approach that spans across different layers of the network stack. In this paper we study how to integrate an efficient method for vertical handoff and adaptation support for multimedia streaming through heterogeneous networks. We also present experimental results obtained with our prototype on IEEE 802.11 and UMTS networks.
