CAREER: Towards Seamless Mobility in Cognitive Radio Wireless Networks

认知无线电技术是一种很有前途的技术，它通过允许动态的频谱接入来克服频谱接入需求的增加和频谱利用效率低下之间的不平衡。无缝移动性被认为是确保认知无线网络（CRN）部署成功的关键组成部分，但不幸的是，在文献中尚未得到充分探讨。该项目的研究目标是开发新的策略和算法，为认知无线网络（crn）提供无缝移动支持。该方法涉及识别crn中频谱环境变化带来的移动性支持新问题，利用时间和空间域的频谱机会变化，主动利用频谱机会进行移动性准备，并通过频谱自适应移动性管理方案优化性能。该项目将为CRN技术的众多应用提供创新的移动性支持技术。它还将对具有高移动性场景的新兴技术的研究产生重大影响，例如车载网络和异构无线网络的机会互联。该项目为研究生和本科生提供了一个获得宝贵的教育培训和研究经验的绝佳机会。研究结果将在IEEE期刊和国际会议上发表。此外，PI计划组织研讨会和期刊特刊，以加强对无线网络无缝移动的理解和促进研究讨论。

The cognitive radio technology is a promising technology to overcome the imbalance between the increase in the spectrum access demand and the inefficiency in the spectrum usage by allowing dynamic spectrum access. Seamless mobility is considered as a critical component to ensure the success of cognitive radio network (CRN) deployment, but unfortunately, is under-explored in the literature. The research objective of this project is to develop new policies and algorithms for providing seamless mobility support in cognitive radio wireless networks (CRNs). The approach involves identifying the new issues in the mobility support caused by the changing spectrum environment in CRNs, exploiting the varying spectrum opportunities in time and space domains, proactively utilizing the spectrum opportunities for mobility preparations, and optimizing the performance via spectrum-adaptive mobility management schemes.This project will provide innovative mobility support techniques to numerous applications of the CRN technology. It will also have significant impacts on research in emerging technologies with high mobility scenarios, such as vehicular networks, and opportunistic interconnections of heterogeneous wireless networks. This project provides an excellent opportunity for graduate and undergraduate research students to gain valuable educational training and research experiences. The research results will be presented at IEEE journals and international conferences. In addition, the PI plans to organize a workshop and a journal special issue to enhance the understanding and promote research discussions on seamless mobility in wireless networks.
