MRI: Development of a Hybrid Wireless Network Infrastructure for Integrated Research and Education

提案#：CNS09-23188PI(S)：杜晓江；Reinholz，Aron J.机构：北达科他州州立大学法戈分校标题：mri/Acq.：开发用于综合研究和教育的混合无线网络基础设施建议：该项目将在现有的异构传感器网络试验床上开发混合无线网络，支持宽带无线网络和通信的研究，从而能够对为HWN设计的协议和方案进行高质量和高精度的性能评估。研究项目包括高效的服务质量(Qos)提供和HWN中的正交频分多址(OFDMA)资源分配，这些项目有望在优化整个系统的性能(例如吞吐量)的同时满足个人用户的Qos要求。虽然传统无线网络中的Qos支持和蜂窝网络中的OFDMA资源分配已经得到了很好的研究，但在HWN中，Qos路由和OFDMA资源分配是高度相关的，这一问题值得进一步探讨。HWN为该机构和附近大学的计算机科学和电气工程专业的教职员工和学生以及该机构纳米科学与工程中心的65名工作人员提供服务。这项工作旨在将教育和培训环境的各个方面与创新研究整合到一个具有凝聚力的无线网络和通信教育方案中。广泛的影响：支持的教育和培训活动包括-招募代表不足的群体的学生参与研究，以及指导-开发一门无线网络和通信的新课程-整合研究和教育美国原住民、女性、低收入和第一代学生将特别针对这个EPSCoR州，在该州，31%的本科生人口低于低收入美国公民的门槛。

Proposal #: CNS 09-23188PI(s): Du, Xiaojiang; Reinholz, Aron J.Institution: North Dakota State University - FargoTitle: MRI/Acq.: Dev.of a Hybrid Wireless Network Infrastructure for Integrated Research and Education Project Proposed:This project, developing a Hybrid Wireless Network (HWN) to be built on top of an existing Heterogeneous Sensor Network (HSN) testbed, supports research in broadband wireless networking and communication enabling high-quality and high-accuracy performance evaluations of protocols and schemes designed for HWNs. Research projects include- Efficient Quality of Service (QoS) provisioning and- Orthogonal Frequency Division Multiple Access (OFDMA) resource allocation in HWNs.These projects are expected to satisfy individual user's QoS requirements while optimizing the performance (e.g., throughput) of the overall system. Although QoS support in traditional wireless networks and OFDMA resource allocation in cellular networks have been well studied, in HWNs QoS routing and OFDMA resource allocation are highly correlated and the problem lends itself to further exploration. The HWN services faculty and students in Computer Science and Electrical Engineering and 65 staff researchers at the Center for Nanoscale Science and Engineering at the institution and nearby universities. The work aims at integrating various aspects of educational and training environment with innovative research into a cohesive package for education in wireless networking and communication.Broader Impacts: Supported education and training activities include - Recruiting students of underrepresented groups to participate in the research, as well as mentoring- Developing a new course in Wireless Networking and Communications- Integrating research and educationNative American, female, low income, and first generation students will be specifically targeted in this EPSCoR state where 31% of the undergraduate populations falls below the threshold for low-income US citizens.
