MRI: Acquisition of a Testbed for Optical/Wireless Integration

该项目旨在建设光/无线融合试验台，以满足下一代通信系统的需求，提供随时随地无处不在的高数据速率接入。现有的异构网(包括光高速SONET、3G蜂窝、无线局域网(WiFi)、即将推出的WiMAX等)的融合，需要针对高效融合的体系结构设计、移动性管理、网络管理、资源管理、计费模型等问题提出新的解决方案。本工作涉及三种接入网络(WiMAX over Sonet/WDM到WiFi接入网、3G仿真网络和WiMAX Over光学扩展网络)，开发了一个原型测试台，即一个仿真环境来评估实用性。该试验台不仅支持光/无线融合的研究，而且支持各个独立网络的研究。具体地说，该工具旨在支持以下研究。通过WiMAX、3G和SONET的集成进行下一代通信网络的系统设计，基于光/无线融合的新型无线网络规划策略，无线/有线网络的带宽管理，UMTS(WCDMA)和WLAN的无缝集成，设计和开发OFDM通信系统中的认知干扰，MIMO通信系统中的干扰避免，下一代光网络的安全流量工程，具有多媒体服务的3G蜂窝网络的资源分配，以及WiFi网络的网络管理。

This project, building a testbed for optical/wireless integration, aims at meeting the need of next generation communication systems, providing high data rates with ubiquitous access anytime anywhere. The integration of existing heterogeneous networks (including optical high-speed SONET, 3G cellular, Wireless LAN (WiFi), the forthcoming WiMAX, etc.), demands new solutions to issues such as architecture design for efficient integration, mobility management, network management, resource management, billing models, etc. This work, involving three kinds of access networks (the WiMAX over Sonet/WDM to WiFi access network, a 3G emulation network, and WiMAX over optical extension network), develops a prototype test bed, namely an emulation environment to evaluate practicality. The testbed supports research not only in the Optical/Wireless integration, but also in each stand-alone network. Specifically, the instrumentation aims at supporting the following research. System design for next-generation communication networks by integrating WiMAX, 3G and SONET, Novel wireless network planning strategy based on optical/wireless integration,Bandwidth management in wireless/wireline networks,Seamless integration of UMTS (WCDMA) and WLAN,Design and development cognitive jamming in OFDM communications systems,Jamming avoidance in MIMO communications systems,Secure traffic engineering for next-generation optical networks,Resource allocation for 3G cellular networks with multimedia services, andNetwork management for WiFi networks.
