Ubiquitous multimedia service provisioning over heterogeneous wireless networks in a diverse mobility landscape

点击翻译按钮获取中文摘要

This proposed research will investigate the delivery of high-quality multimedia services over wireless networks in a diverse mobility landscape. The service delivery will be enabled ubiquitous (i.e., anywhere and anytime) by using diverse wireless technologies. In recent years, wireless networks have been proliferating and offering a variety of access choices. Next-generation wireless networks are envisioned to be heterogeneous, integrating multiple broadband wireless accesses and providing "always best connectivity." Although there are some initial efforts by cellular carriers to provide multimedia services, they are still embryonic and far from profitable. In this project, we will develop a spectrum of techniques to facilitate multimedia communications over heterogeneous wireless networks. It will effectively address emerging new challenges in hostile wireless environments such as high mobility and error-prone transmissions. The limited network bandwidth will be intelligently allocated to mobile users to enable cost-effective multimedia services with a satisfactory quality.
