A Pilot Study on Cognitive Acoustic Underwater Networks (CAUNet) for Sustainable Ocean Monitoring and Exploration, 2013/10/01-2015/09/30, An underwater cognitive acoustic network (CAUNet) is proposed in this project. CAUNet will be aware of the coexistence of multiple underwater acoustic systems to preserve a sustainable blue ocean for next generations. The project goals include investigating acoustic spectrum usage via data collection and analysis, designing algorithms, software and hardware for acoustic spectrum sensing and spectrum management, and evaluating the feasibility and performance of the proposed work via simulations, and lab and field experiments.

Acoustic Sensor Networks for Ice-Covered Seas, 2014/01/01-2016/12/31, This project proposes to design and develop an integrated underwater acoustic sensor network for ice-covered. It will transmit data wirelessly through acoustic waves from sub-surface ocean sensors to a receiving array with a surface connection to satellites and the Internet. This project will expand the capabilities of studying sea ice changes in the transition zone by developing and deploying an underwater wireless communication network for the arctic area.

Ocean-TUNE: A Community Ocean Testbed for Underwater Wireless Networks, 2012/06/01-2015/05/31, This project involves the design and deployment of an open underwater testbed suite, accessible to the public at four sites in Connecticut, California, Texas, and Washington States. The testbed will include flexible choices of surface nodes, bottom nodes, and mobile nodes with reconfigurable modems. It will enable the vision of remote controlled and continuous networked node deployments running tests of communication, networking, sensing, and data streaming.

Efficient MAC Protocols for UWNs, Medium access control (MAC) protocols determine how nodes in the network share the underlying communication channel and are quite important to the network performance. In this effort, he investigated different MAC protocols, including parallel reservation based MAC and the multi-channel MAC protocols for underwater networks. To fully utilize the available bandwidth, Dr. Peng proposed a novel MAC protocol, called COPE-MAC. And together with his colleagues, several new MAC protocols are also designed based on our field test experience.

Security Issues in UWNs, Like the terrestrial wireless networks, underwater wireless networks are inherently vulnerable to attacks due to the broadcast nature. However, underwater wireless networks have their special characteristics that require new design in encryption, attack detection, self-protection, defending and recovering. UWN security now becomes an interesting topic in UWSN lab. Preliminary work has been done to study the effectiveness of different types of attacks. This is an area Dr. Peng is keenly interested in exploring more.

Aqua-TUNE: a Field Testbed for Underwater Wireless Networks (UWNs), Aqua-TUNE, a field Testbed for Underwater Network Experiments, is presented in this work. The testbed has a network of acoustically connected nodes. Each node contains a ﬂoating platform for electronic devices, an acoustic modem, a RF based remote control system and the software platform that accommodates the protocols for underwater networks. Aqua-TUNE offers a variety of services that open much potential to the researchers and application developers. The testbed is designed to be affordable, accessible and easy to handle. Aqua-TUNE can be used to experimentally evaluate algorithms and protocols designed for underwater networks in real world scenarios. It is a valuable tool which leads to Ocean-Tune.

Aqua-Sim：Simulators for UWNs, As of 2006, there was no discrete-event based network simulator for underwater acoustic networks. In this effort, based on NS-2, Aqua-Sim, a new network simulator for UWSNs, was developed. Aqua-Sim accurately models the underwater acoustic channel, the three-dimensional topology and the mobility pattern of underwater objects. A bunch of protocols (from the physical layer to the application layer) have been implemented in Aqua-Sim and new protocols can be easily imported into Aqua-Sim because of its open architecture. In 2012, he is working with colleagues from another university in designing a new simulator which will provide a more accurate channel and in the meantime significantly reduce developers' workload.

Aqua-3D：3D Visualization for UWN Simulations, In this project, a network visualization tool to enable 3D visualization for underwater wireless network simulations is developed. It helps researchers using Aqua-Sim understand the simulation progress in a more intuitive way. When combined with Aqua-Net, it can also demonstrate network events and activities after, or even during, field tests in 3D. The visualization tool is designed to be user friendly, especially to NAM users, as it is designed to follow the interfaces and functions similar to NAM. Future work includes fully functional capabilities for visualization and much improved user interfaces.

Aqua-Net：the Network Architecture of UWNs, Aqua-Net is an open architecture for UWNs. It aims to provide a powerful networking solution kit for underwater wireless network researchers. In Aqua-Net, BSD socket-like interface makes it easy for end users to implement applications. And due to its layered structure, new protocols can also be plugged into the system. Through a detailed case study on MAC, he demonstrates the potential power of Aqua-Net. The future work is to implement more protocols to populate the protocol stack. Meanwhile, he is working to identify new needs from the community and trying to provide better support for the latest software and hardware. Aqua-Net will evolve as the underwater network research proceeds. And it is considered as a groundwork and valuable tool for future advances of the underwater sensor network research.

Aqua-Lab：the Lab Testbed for UWNs, In this project, he designed and implemented a lab testbed for underwater wireless networks. This system was built to explore the various properties of and to test and develop theories for underwater sensor networks, with an initial focus on real parameters in the underwater channel and characterizing the performance this has on an underwater sensor network. The testbed has been developed by ﬁrst constructing the physical acoustic environment in the lab and providing APIs to the potential users. By introducing the concept of virtual nodes, the topology that has the maximal degree equals the number of modems available could be emulated. Some experiment results have also been collected. In addition, a geographic routing protocol called VBF has been implemented based on the APIs he provides for the testbed. This testbed makes it possible for researchers to get more experience designing and implementing applications for realistic underwater environment before doing something sophisticated and interesting.
