CAREER: Leveraging Smart Antennas for WiMAX-based Mesh Networking

WiMAX技术（IEEE 802.16）可以为各种应用提供高速、远程的无线通信。智能天线，如数字自适应阵列（DAA）和多输入多输出（MIMO）天线，可以提供较长的传输范围，并通过干扰抑制和空间复用来提高网络容量。该项目的目标是通过研究调度、路由和中继站放置等基本问题，为具有智能天线的WiMAX网状网络提供全面的网络解决方案。具体来说，将研究它们的计算复杂性，并提出有效且符合标准的算法和协议来解决它们。PI还将在OPNET建模器中开发一个中继站模型，以及一个基于DAA天线的测试平台，以评估和验证提出的解决方案。本项目提出的算法和协议可应用于WiMAX产品开发，并有望对IEEE和IETF的标准化活动产生影响。中继站模型和试验台可供其他研究人员进行评估和验证。此外，拟议的研究活动将补充和丰富关于无线通信和网络的课程。

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.
