Wireless communication networks: network interworking, and resource, mobility and traffic management

拟议的研究将调查混合无线/有线网络（例如，无线局域网、蜂窝和互联网）和互联无线网状网络（如WiFi （IEEE 802.11系列）和WiMAX （IEEE 802.16系列））中的资源、移动性和流量管理问题。长期目标是发展深入的知识，以建立一个灵活和强大的跨域互联网络架构，即一个信息传输平台，用于在固定和移动环境中处理多媒体服务。短期目标是(i)研究通过信道估计获得的部分信道状态信息的合作分集，（ii）研究认知无线电中的动态频谱接入，（iii）研究互联无线网状网络的跨层设计和优化，以及（iv）开发无线互联网的建模和分析方法。短期目标的结果将成为实现长期目标的基石。

The proposed research will investigate into resource, mobility and traffic management issues in hybrid wireless/wireline networks (e.g., wireless LANs, cellular and Internet) and interworked wireless mesh networks such as WiFi (IEEE 802.11 series) and WiMAX (IEEE 802.16 series). The long term objective is to develop in-depth knowledge towards the construction of a flexible and robust cross-domain internetworking architecutre, i.e., an information transport platform, for handling multimedia services in fixed and mobile environments. The short term objectives are to (i) investigate cooperative diversity with partial channel state information, to be acquired via channel estimation, (ii) investigate dynamic spectral access in cognitive radio, (iii) investigate cross-layer design and optimization for interworked wireless mesh networks, and (iv) develop modeling and analysis methods for wireless Internet. The results from the short term objectives will form the building blocks toward fulfillment of the long term objective.
