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.

这项拟议的研究将调查在各种移动性领域中通过无线网络上高质量的多媒体服务的交付。通过使用各种无线技术，将启用服务交付的无处不在（即任何时间和任何时间）。近年来，无线网络一直在扩大并提供各种访问选择。下一代无线网络被设想为异质，集成了多个宽带无线访问，并提供了“始终最好的连接”。尽管蜂窝载体在提供多媒体服务方面做了一些初步的努力，但它们仍然是胚胎，远非盈利。在这个项目中，我们将开发一系列技术，以促进异质无线网络的多媒体通信。它将有效地解决敌对无线环境中的新挑战，例如高移动性和容易出错的传输。有限的网络带宽将智能分配给移动用户，以启用具有令人满意的质量的具有成本效益的多媒体服务。
