The infrastructure, based on open research platforms, consists ofa testbed that enables wide and systematic experimental evaluation and comparison ofunderwater acoustic networks. The work, involving this rapidly deployable testbed thatcan be shared by the underwater networking community, aims to demonstrate the abilityof the facility to facilitate field experiments. The project represents a higher-levelcollaborative that arose from two collaborative groups. One group developing thefacility, the other working mainly on the experiments utilizing the facility. The testbed isexpected to be a buoy-based system that can be easily taken to different environments.When operational, these systems will be deployed 5 or 6 times a year. Theinfrastructure will consist of two types of nodes with different capabilities. The first typeof node of the rapidly deployable testbed will offer a fixed physical layer capability usingacoustic modems such as the WHOI micromodem or the ISI S-modem to implement aphysical layer with limited reconfigurability interfaced to a reconfigurable networkprocessor. This network processor will support algorithm/protocol implementation andtesting at higher network layers. The Network functions on the Fixed Physical Layertestbed will be hosted by a Gumstix processor which will then communicate withphysical layer modems such as the WHOI Micromodem or USC/ISI S-modem via aserial port. Ten to fifteen fixed physical layer nodes will be built including up to 3gateway nodes. Each gateway node of the testbed will be equipped with wireless RFcommunication enabling real-time monitoring and control of network performance. Thefixed physical layer nodes will be smaller and more easily deployed than the secondtype of node which is the all-layer node. The all-layer node is a more capable node thatwill ultimately support algorithm/protocol implementation and acoustic data collection atall networking layers. In addition to the equipment included in the fixed physical layernodes (i.e., a gumstix network processor and the ability to support relatively fixedphysical layer modems such as the WHOI Micromodem and the ISI S-modem), theall-layer nodes will also include a general purpose data acquisition system (D/A andA/D) with substantial disk storage and in-situ processing capability. The MIT r-modemsoftware will be implemented on this general purpose hardware and, along withMATLAB, will enable user implementation and testing of algorithms and the gathering ofacoustics data at the physical layer in addition to the testing at higher network layersthat it will share in common with the fixed physical layer nodes. Three to five all-layernodes will be built. The rapidly deployable testbed, using two types of nodes withvarying capabilities, should significantly enhance research at all network layers whilesetting the stage for future infrastructure improvements.Many research groups investigating fundamental questions about how to design suchnetworked systems that utilize acoustic communications in complex underwaterenvironments have had their overall effort significantly slowed by the lack of commonmeans to test and compare protocols under realistic environmental conditions. Thisinfrastructure responds to the need for consensus on analytic or simulation models forunderwater networks where researchers need the ability to gather experimental dataunder real world conditions in order to make progress.The network stack will be modular by design with sockets used to enable cross layercontrol and communication. The physical, MAC, Network and Application layers will bepopulated with sample components to enable users test their own algorithms orprotocols without having to populate the entire stack. Users will be able to write modulesto test their own algorithms or protocols at different layers and selectively replace thesample modules with their own. While the development of the modular architecture andsample modules for the network stack will be done with close coordination between allparticipating institutions, the lead institution for the layers that will be provided arePhysical Layer (MIT for the all-layer system, WHOI for the Fixed-PHY system), MACLayer (USC/ISI), Network Layer (UConn, a geo-routing protocol), and Application Layer(UMass, a DTN routine service). The open characteristic of the testbeds and theirusefulness for conducting research will be demonstrated by the members of the team(primarily UConn and UMass as described above) and a few selected outsideparticipants. In addition, acoustic receptions suitable for physical layer research will bemade available to the general research community via the Internet.Broader Impacts: This work enables the essential capability of research groups toexamine fundamental research questions and their potential solutions in the real world.The infrastructure will directly benefit many on-going research projects in this field Alarge number of potential users in the community may benefit from this testbedinfrastructure. In addition to the significant research impact, the infrastructure isexpected to make a very strong educational impact as well, supporting classes bringingremote access to field experiments to students for whom traditional experiments wouldhave been too costly. The infrastructure can accelerate research and education in theunderwater networking field.

Freitag, LeeRajasekaran,Sanguthevar；施,Zhijie;威利•彼得•k;标题：合作项目：CRD/IAD：水下自组织和传感器网络（ORTUN）的开放式研究试验台。该合作项目为水下网络社区开发了第一个开放式试验台基础设施，使开放访问具有远程进行实验的能力。该基础设施基于开放式研究平台，包括一个测试平台，可以对水声网络进行广泛和系统的实验评估和比较。这项工作涉及这个可由水下网络社区共享的快速部署测试平台，旨在展示该设施促进现场实验的能力。该项目代表了由两个协作组产生的更高层次的协作。一组开发设备，另一组主要利用设备进行实验。试验台预计将是一个浮标系统，可以很容易地带到不同的环境中。当这些系统投入使用时，每年将部署5到6次。该基础设施将由两种具有不同功能的节点组成。快速部署试验台的第一种类型的节点将提供固定的物理层能力，使用声学调制解调器，如WHOI微调制解调器或ISI s -调制解调器来实现具有有限可重构接口的物理层，并与可重构网络处理器连接。该网络处理器将支持更高网络层的算法/协议实现和测试。固定物理层测试台上的网络功能将由一个Gumstix处理器承载，然后该处理器将通过串行端口与物理层调制解调器（如WHOI Micromodem或USC/ISI S-modem）进行通信。将建立10到15个固定物理层节点，包括多达3个网关节点。试验台的每个网关节点将配备无线射频通信，能够实时监控和控制网络性能。固定的物理层节点将比第二种类型的节点（全层节点）更小，更容易部署。全层节点是一个功能更强大的节点，最终将支持所有网络层的算法/协议实现和声学数据收集。除了固定物理层节点中包含的设备（即，gumstix网络处理器和支持相对固定的物理层调制解调器的能力，如WHOI Micromodem和ISI S-modem）之外，全层节点还将包括具有大量磁盘存储和现场处理能力的通用数据采集系统（D/ a andA/D）。MIT r-modemsoftware将在这个通用硬件上实现，并且与matlab一起，将使用户能够实现和测试算法，并在物理层收集物理数据，以及在更高的网络层进行测试，它将与固定的物理层节点共享。三到五个全层节点将被构建。快速部署的测试平台，使用两种类型的节点，具有不同的功能，应该显著加强所有网络层的研究，同时为未来的基础设施改进奠定基础。许多研究小组正在研究如何在复杂的水下环境中设计这种利用声学通信的网络系统的基本问题，由于缺乏在现实环境条件下测试和比较协议的通用方法，他们的总体努力大大放慢了。该基础设施响应了对水下网络分析或模拟模型达成共识的需求，研究人员需要在现实世界条件下收集实验数据的能力，以便取得进展。网络栈将采用模块化设计，套接字用于实现跨层控制和通信。物理层、MAC层、网络层和应用层将使用示例组件填充，以便用户无需填充整个堆栈即可测试自己的算法或协议。用户将能够编写模块来测试自己在不同层的算法或协议，并有选择地用自己的模块替换样本模块。虽然网络堆栈的模块化架构和示例模块的开发将在所有参与机构之间的密切协调下完成，但将提供的层的牵头机构是物理层（MIT为全层系统，WHOI为固定phy系统），MACLayer (USC/ISI)，网络层（UConn，地理路由协议）和应用层（UMass， DTN常规服务）。试验台的开放特性及其对开展研究的有用性将由团队成员（主要是如上所述的康涅狄格大学和马萨诸塞大学）和一些选定的外部参与者来展示。此外，适合物理层研究的声学接收器将通过互联网提供给一般研究界。更广泛的影响：这项工作使研究小组能够在现实世界中检查基础研究问题及其潜在解决方案的基本能力。该基础设施将直接使该领域的许多正在进行的研究项目受益，社区中的大量潜在用户可能会从该测试基础设施中受益。除了显著的研究影响外，基础设施预计也将产生非常强大的教育影响，支持课程将远程访问现场实验带给那些传统实验过于昂贵的学生。该基础设施可以加速水下网络领域的研究和教育。
