CAREER: Leveraging Smart Antennas for WiMAX-based Mesh Networking

WiMAX技术（IEEE 802.16）可以为各种各样的应用提供高速和长距离的无线通信。智能天线，如数字自适应阵列（DAA）和多输入多输出（MIMO）天线，可以提供一个长的传输范围，并通过干扰抑制和空间复用提高网络容量。本项目的目标是提供一个全面的网络解决方案的WiMAX网状网络与智能天线通过调查的基本问题，包括调度，路由和中继站的位置。具体来说，他们的计算复杂性将进行调查，并提出有效的和标准兼容的算法和协议来解决这些问题。PI还将在OPNET Modeler中开发一个中继站模型，以及一个基于DAA天线的测试平台，以评估和验证所提出的解决方案。该项目中提出的算法和协议可以应用于WiMAX产品开发，并有望影响IEEE和IETF的标准化活动。中继站模型和测试平台可以被其他研究人员用于评估和验证。此外，拟议的研究活动将补充和丰富无线通信和网络课程。

The WiMAX technology (IEEE 802.16) can provide high-speed and long-range wireless communications for a large variety of applications. Smart antennas, such as Digital Adaptive Array (DAA) and Multiple Input and Multiple Output (MIMO) antennas, can offer a long transmission range and improve network capacity via interference suppression and spatial multiplexing. The objective of this project is to provide a comprehensive networking solution for a WiMAX mesh network with smart antennas by investigating the fundamental problems, including scheduling, routing and relay station placement. Specifically, their computational complexities will be investigated, and efficient and standard-compliant algorithms and protocols will be proposed to solve them. The PI will also develop a relay station model in the OPNET Modeler, and a DAA antenna based testbed to evaluate and validate the proposed solutions.The algorithms and protocols proposed in this project can be applied in the WiMAX product development and are expected to impact the standardization activities in IEEE and IETF. The relay station model and the testbed can be used by other researchers for evaluation and validation. Moreover, the proposed research activities will complement and enrich the curriculum on wireless communications and networking.
