In a thin client computing environment, applications run on server farms and are accessed through thin client protocols like Remote Frame Buffer (RFB), or Remote Desktop Protocol (RDP). Although they work well in high and stable bandwidth networks, thin client protocols require some modifications to adapt to the varying characteristics of wireless networks and to reduce the energy consumption of thin...
Nowadays, technologies are providing the mobile terminals with much more powerful computational abilities. Such improvement made it possible to run many complex applications on mobile devices. However, many of these new applications are also resources demanding. Lacking sufficient resources would cause performance failures and impact negatively on the users' quality of experience. In order to improve...
Multimedia content sharing services, such as YouTube, usually offer only low quality video streams. Additionally, it is expected the popularity of these services will increase even further in the future. Therefore, current streaming- content delivery architectures, with centralised searching and management components, might not be able to keep up with the ever-growing user bases. In this paper, we...
More and more, multimedia services are being accessed via fixed and mobile networks. These services are typically much more sensitive to packet loss, delay and/or congestion than traditional services. In particular, multimedia data is often time critical and, as a result, network issues are not well tolerated and significantly deteriorate the userpsilas quality of experience (QoE). We therefore propose...
The access network has become an infrastructure for delivery of multimedia services, such as broadcast TV, voice over IP or video conferencing, to residential users . Compared to more traditional IP services such as e-mail, users demand a higher quality of experience (QoE) for these new services. To guarantee the quality of service (QoS), access network providers have deployed several service enablers,...
