U.S.-India Cooperative Research: Multichannel Multihop Wireless LANs for Rapid Deployment

该合同支持美印合作研究：用于快速部署的多通道多跳无线局域网。纽约州立大学石溪分校（SUNY）的Samir Das教授和浦那高级计算发展中心（C-DAC）网络和互联网软件组的Vasant Avaghade教授提出了一项实验研究，以开发多跳无线局域网（WLAN）架构的原型。他们的目标是使方案对客户端设备完全透明，这样就不需要使用带有无线链路的客户端节点通过接入点（ap）连接到有线网络。他们将探索在每个AP的多个无线电接口上使用多个信道，以获得容量增强，并开发和分析信道分配问题和协议。他们还计划研究可以关闭一些接入点的调度算法，以便在延长网络寿命的同时保持覆盖范围。范围：印度的合作机构C-DAC，几十年来一直是先进计算的领先研究中心，目前处于网络和互联网技术研发的前沿。该项目将加强C-DAC与纽约州立大学之间的合作，双方都将从合作伙伴提供的互补专业知识中受益。C-DAC在实施研究原型方面有长期的经验；纽约州立大学的专长在于网络、协议开发和分析方面的基础研究。该项目将对降低印度等“发展中”国家电信基础设施和服务的部署成本产生影响，并将有助于缩小能够和不能有效使用新信息和通信工具的人之间的“数字鸿沟”。

Professors Samir Das, State University of New York at Stony Brook (SUNY) and Vasant Avaghade, Networking and Internet Software Group, Center for Development of Advanced Computing (C-DAC), Pune propose an experimental study to develop a prototype multihop wireless local area network (WLAN) architecture. Their goal is to make the scheme completely transparent to client devices so that it will be unnecessary to use client nodes with wireless links to connect to a wired network through Access Points (APs). They will explore use of multiple channels on multiple radio interfaces in each AP to get a capacity enhancement, and develop and analyze channel assignment issues and protocols. They also plan to study scheduling algorithms that can power off some APs so that coverage can be maintained while extending the lifetime of the network. Scope: The collaborating institution in India, C-DAC, has been a leading research center for advanced computing for several decades and currently is at the forefront of R&D in networking and internet technologies. This project will enhance collaboration between C-DAC and SUNY and both institutions stand to benefit from the complementary expertise offered by each partner. C-DAC has long experience in implementing research prototypes; SUNY's expertise lies in basic research in networking, protocol development and analysis. This project will have an impact on lowering the deployment costs of telecommunication infrastructure and services in "developing" countries such as India and will contribute to reducing the "digital divide" between those who can and cannot use new information and communication tools effectively.
