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

提案号：CNS 09-23188PI(s)：杜晓江；机构：北达科他州立大学- fargotle: MRI/Acq。提案：该项目开发一个混合无线网络（HWN），将建立在现有的异构传感器网络（HSN）测试平台之上，支持宽带无线网络和通信的研究，使为HWN设计的协议和方案能够进行高质量和高精度的性能评估。研究项目包括HWNs中的高效服务质量（QoS）提供和正交频分多址（OFDMA）资源分配。这些项目预计将满足个别用户的QoS需求，同时优化整个系统的性能（例如，吞吐量）。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HWNs中，QoS路由和OFDMA资源分配是高度相关的，这个问题还有待进一步探索。HWN为计算机科学和电气工程专业的教师和学生以及该机构和附近大学纳米科学与工程中心的65名研究人员提供服务。这项工作旨在将教育和培训环境的各个方面与创新研究结合起来，形成一套具有凝聚力的无线网络和通信教育方案。更广泛的影响：支持的教育和培训活动包括-招募代表性不足的群体的学生参与研究，以及指导-开发无线网络和通信的新课程-整合研究和教育在这个EPSCoR州，美国原住民，女性，低收入和第一代学生将被特别针对，其中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.
