MRI: Acquisition of a Testbed for Optical/Wireless Integration

本项目旨在建立一个光/无线集成的试验平台，以满足下一代通信系统的需要，提供高数据速率和随时随地的无处不在的接入。现有异构网络（包括光学高速SONET、3G蜂窝、无线LAN（WiFi）、即将到来的WiMAX等）的集成，本文针对WiMAX over Sonet/WDM to WiFi接入网、3G仿真网和WiMAX over Optical Extension网这三种接入网，开发了一个原型测试床，即一个仿真环境来评估其实用性。该测试平台不仅支持光/无线集成的研究，还支持每个独立网络的研究。具体而言，仪器旨在支持以下研究。集成WiMAX、3G和SONET的下一代通信网络的系统设计，基于光/无线集成的新型无线网络规划策略，无线/有线网络中的带宽管理，UMTS（WCDMA）和WLAN的无缝集成，OFDM通信系统中认知干扰的设计和开发，MIMO通信系统中的干扰避免，下一代光网络的安全流量工程，支持多媒体业务的3G蜂窝网络的资源分配和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.
