MRI: Acquisition of a Testbed for Optical/Wireless Integration

本项目旨在构建光/无线融合的试验台，以满足下一代通信系统的需求，提供高数据速率和无处不在的随时随地接入。现有异构网络（包括光纤高速SONET、3G蜂窝网络、无线局域网（WiFi）、即将到来的WiMAX等）的集成需要新的解决方案来解决诸如高效集成的架构设计、移动性管理、网络管理、资源管理、计费模型等问题。本工作涉及三种接入网（WiMAX over Sonet/WDM to WiFi接入网、3G仿真网和WiMAX over optical extension网），开发了一个原型测试平台，即仿真环境来评估实用性。该试验台不仅支持光/无线集成的研究，也支持各个独立网络的研究。具体而言，该仪器旨在支持以下研究。集成WiMAX、3G和SONET的下一代通信网络系统设计基于光/无线集成的新型无线网络规划策略、无线/有线网络的带宽管理、UMTS （WCDMA）与WLAN的无缝集成、OFDM通信系统的认知干扰设计与开发、MIMO通信系统的干扰避免、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、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.
