BRIGE: Heterogeneous Traffic over Heterogeneous Relay Networks

派：刘，凌佳研究所：堪萨斯大学题目：桥：异质中继网络上的异质流量abSTRACT智能优点：异质网络，特别是异质中继网，被认为是未来宽带移动通信的使能技术之一。以往的此类网络设计往往忽略了统计排队时延在性能分析中的作用。然而，未来宽带移动数据网络的大部分业务将是时延敏感的，而大多数时延敏感的应用对统计时延违规概率有严格的要求。例如，在第四代蜂窝标准中，对实时视频业务的时延违规概率要求为2%，而无线接入网的时延界限为50ms。Brige研究的目的是为统计时延约束(时延违规概率约束)下的异类中继网络的分析和设计提供一个统一的基本框架。该项目的研究部分由两部分组成。第一部分主要研究无线多跳中继系统的统计时延分析，为分析时延违规概率约束下的无线系统性能提供一个统一的框架。第二部分关注的是异类中继网络，其中将确定新的移动关联策略和负载均衡方法，以最大化异类中继网络的整体网络效率。广泛影响：移动无线设备是社会不可或缺的一部分，目前全球超过75%的人口使用移动无线设备。在美国，目前移动设备的采用率超过92%。提高它们性能的研究提供了改善这些设备如何满足用户需求的潜力。除了全球技术影响，国际和平研究所还提出了一项教育计划，让当地学生，特别是来自代表不足的群体的学生，沉浸在令人兴奋的无线通信领域。国际和平协会的外展活动从高中阶段一直到研究生阶段。国际学生联合会还将招收代表不足的群体的学生，包括西班牙裔、女性、低收入学生和第一代学生参与该项目。通过将研究和教育结合在一起，该项目将扩大未被充分代表的群体在工程学领域的参与。

PI: Liu, LingjiaInstitution: University of KansasTitle: BRIGE: Heterogeneous Traffic over Heterogeneous Relay NetworksABSTRACT Intellectual Merit: Heterogeneous networks, especially heterogeneous relay networks, are believed to be one of the enabling technologies for future broadband mobile communications. Previous design of such networks usually neglects the role of statistical queueing delay in performance analysis. However, most traffic of future broadband mobile data networks will be delay-sensitive while most delay-sensitive applications have stringent requirements on statistical delay-violation probabilities. For example, in the 4th generation cellular standard, the requirement on delay-violation probability for real-time video traffic is 2% with the delay bound being 50ms for radio access networks. The objective of this BRIGE research is to provide a unified fundamental framework for the analysis and design of heterogeneous relay networks under statistical delay constraints (constraints on delay-violation probabilities). The research components of the project consist of two parts. The first part focuses on the statistical delay analysis of wireless multi-hop relay systems to provide a unified framework to analyze wireless system performance under delay-violation probability constraints. The second part focuses on heterogeneous relay networks where new mobile association strategies and load balancing methods will be identified to maximize the overall network efficiency for a heterogeneous relay network.Broader Impacts: Mobile wireless devices are an integral part of society and are currently used by over 75% of the global population. In the United States, the present adoption rate of mobile devices exceeds 92%. Research that leads to improving their performance offers the potential to improve how these devices serve the needs of their users. In addition to global technological impact, the PI also proposes an educational plan that will immerse local students especially from the underrepresented groups in the exciting field of wireless communications. The PI's outreach activities span from the high school level up through the graduate level. The PI will also recruit students of underrepresented groups including Hispanic, female, low incoming and first generation students to participate in the project. By integrating research and education together, this project will broaden the participation of underrepresented groups in engineering.
