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.

MIT R-ModemSoftware将在此通用硬件上实现，并且与Matlab一起，将启用用户实现和测试算法，以及在物理层的Acustrics数据收集，除了在较高网络层的测试外，它将与固定层的NODES共享。将建造三到五个全层。使用两种具有不同功能的节点的快速部署测试床，应显着增强所有网络层的研究，以确保未来的基础设施改进的阶段。许多研究小组调查了有关如何设计有关如何设计这种网络系统的基本问题，这些问题可以在整体上逐步审查复杂的环境，从而使整体努力在复杂的环境中逐步审查了速度，使其在复杂的环境中逐步审查了较慢的环境。 状况。该基础设施响应了对杜德沃特网络的分析或模拟模型达成共识的需求，研究人员需要能够收集实验性数据现实世界条件以取得进展的能力。该网络堆栈将通过使用用于启用交叉外衬管和通信的插座的设计模块化。物理，MAC，网络和应用程序层将用样本组件进行填充，以使用户不必填充整个堆栈，因此可以测试自己的算法orprotocols。用户将能够在不同层上编写Modulesto测试自己的算法或协议，并用自己的选择性地替换TheSample模块。 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 服务）。团队成员（如上所述的UCONN和UMass的成员）和一些选择的外部参与者将证明测试床的开放特征及其进行研究的功能。此外，适用于物理层研究的声学接收将通过互联网对通用研究社区进行cor虫。Broader的影响：这项工作使研究小组对验证基础研究问题及其在现实世界中的潜在解决方案的重要能力。基础设施中的潜在解决方案将直接受益于该领域的许多潜在的潜在用户，从而使该社区中的许多持续的研究受益于该测试量的潜在用户。除了重大的研究影响外，基础架构也被指望能够产生非常强大的教育影响，支持班级将领域实验访问到传统实验的成本太高的学生中。基础设施可以加速往返北水网络领域的研究和教育。
