Enabling Seamless Service Provisioning over cooperative heterogeneous wireless networks

这个拟议的项目将研究一套使能技术，以在不同的无线网络上提供无缝、可靠和安全的信息交付服务。为了支持随时随地、以任何方式进行的泛在信息访问，将融合协作智能，有效地整合各种无线接入网络。拟议的研究将解决重大的技术挑战，包括网络异构性、单模或多无线电终端的混合用户群、多跳端到端传输、高网络动态以及容易出错的有损信道。特别是，该项目将制定(1)促进网络合作的通用网络信息收集和同化计划，(2)不同类型无线网络之间合作的有效网络框架，(3)通过多个无线网络无缝提供服务的自适应服务提供机制，以及(4)通过认证合作进行安全通信的有效信息交换机制。它将开发网络协议和控制算法，这些协议和控制算法对于通过具有不同无线接入技术的协作传输平台无处不在地连接移动用户至关重要。

This proposed project will investigate a set of enabling technologies to provide seamless, reliable, and secure information delivery services over heterogeneous wireless networks. To support ubiquitous information access in an anywhere, anytime, and anyhow fashion, cooperative intelligence will be incorporated to effectively integrate various wireless access networks. The proposed research will address significant technical challenges including network heterogeneity, mixed user population of single-mode or multi-radio terminals, multihop end-to-end transmission, high network dynamics, and error-prone lossy channels. In particular, the project will develop (i) a generic network information gathering and assimilation scheme to facilitate network cooperation, (ii) an effective networking framework for cooperation among heterogeneous wireless networks, (iii) adaptive service provisioning mechanisms for seamless service delivery via multiple wireless networks, and (iv) efficient message exchange mechanisms for secure communications with authenticated cooperation. It will develop networking protocols and control algorithms critical for connecting mobile users ubiquitously over a cooperative transport platform with different wireless access technologies.
