Underwater Acoustic Networks: Performance Analysis and Protocol Design
Introduction
| The SIGNET group at the Information Engineering Department of the University of Padova, led by Prof. Michele Zorzi, has been active for some years now in the field of underwater communications and networking. The group features both personnel permanently allocated to the topic and temporary collaborations with students and fellows of other Universities, as well as external collaborations with private institutions. The interests of the SIGNET group are widespread, and span from realistic channel modeling to MAC protocol analysis and design, from channel allocation schemes for channel-aware FDMA to routing and broadcasting in fixed as well as mobile networks. Our activities include, but are not limited to: |
- Channel modeling: we seek compact models, encompassing peculiar underwater channel features that are not typical of radio channels, such as shadow zones, horizontal vs. vertical channel fading, spherical vs. cylindrical propagation and attenuation, etc. In addition we study how to relate environmental factors such as the geographic location, season, type of bottom sediments, surface waves patterns, etc., to channel statistics, in order to drive the design of underwater networking protocols. The models we look for should are meant to be easy enough to be incorporated into network simulators.
This task is carried out in collaboration with institutions and research centers such as the NATO CMRE, WHOI and Scripps, that can provide realistic data from undersea measurement campaigns.
- MAC protocol design and evaluation: we have been analyzing and designing a number of MAC solutions by means of stochastic models, in order to discover which features make one protocol perform better than others. Thanks to tools such as WOSS, specifically designed to provide realistic channel behaviors to simulations, we can perform network simulation in a variety of scenarios. This line of research will eventually lead to the definition of a novel protocol that should include all the best behaviors seen in other approaches.
- Routing protocol design and evaluation: routing in multihop underwater networks may turn out to be a very challenging task, as different underwater applications and tasks may require very different performance in terms of network responsiveness or communications robustness. In some cases, this may require delay-tolerant routing protocols, that work well in the presence of very long propagation delays and intermittent connectivity. Broadcasting also represent a fundamental primitive that will enable baseline (e.g., network reprogramming) as well as priority operations (e.g., alarm spreading, distress calls). We analyzed the relevant routing tradeoffs that allow, e.g., to save energy by choosing wisely which nodes will relay messages; this led to the definition of some routing paradigms that proved to work well in 2D and 3D networks. We also designed several protocols such as SUN, UDTN, UW-Polling, etc., which help manage information routing and data retrieval in generic UW networks where no knowledge of the network topology is available a priori. We are also working towards solutions that make use of some compressed knowledge of the channel gain in order to optimize multihop communications.
- Error control over underwater acoustic links: We have investigated several policies for error control in underwater networks, both over single links and in multiuser networks with multiple access interference. Our work led to the definition of an ARQ policy that reduces the in-order delivery delay over single links, to a study of Hybrid-ARQ implemented using “good” code ensembles over correlated single-link underwater channels, and to USR, a policy that emulates Selective Repeat ARQ over half-duplex underwater channels and works well in multiuser networks.
In the past, we also designed efficient broadcasting techniques based on Hybrid ARQ with a strong FEC component, in order to prevent long retransmission delays.
- Sea trials and experiments: underwater networking is known to be a challenging task, which in turn requires to demonstrate networking protocols and solutions at-sea before claiming that they actually work. In order to make this task easier and to reduce the protocol design-to-experimentation delay, we have designed an interface which makes it possible to reuse network simulator code for at-sea experiments. This interface is becoming more mature by the day, in order to support different modems and network architectures, which yield most diverse requirements in terms of bit rate, MTU, frequency, and language to interface with the modem. Our interface is part of the DESERT Underwater libraries, a full solution for simulation and experimentation of underwater network protocols.
Projects recently completed
The underwarter acoustic networks group is currently involved in several efforts funded by major institutions worldwide. These efforts are typically in the form of 3- to 4-year projects involving up to 10 partners. The three major ongoing projects are:
| CLAM |
The goal of the CLAM project is to develop a collaborative embedded monitoring and control platform for surveillance of underwater equipment. This objective is being pursued by combining cutting edge acoustic vector sensor technology, 1D, 2D, and 3D sensor arrays, underwater wireless sensor networks protocol design, advanced techniques for acoustic communication, new solutions for collaborative situation-aware reasoning and distributed data and signal processing and control for linear sensor arrays. |
|
| NAUTILUS |
The main objective of the NAUTILUS project is to provide a comprehensive study of the technical issues related to the realization of underwater telerobotics, on which a system concept can be based. Specifically, the major outcome of the NAUTILUS project will be a complete solution for a communications and networking architecture for an underwater sensing, monitoring and exploration system comprising intelligent robots that need to perform collaborative missions. The main areas of research addressed will include underwater channel models, efficient acoustic communications, networking protocols (multiple access, routing, transport), and cross-layer protocol design. | |
| ...... |
Robust Acoustic Communications for Underwater Networks (RACUN) is a 4-year effort funded under the umbrella of the European Defence Agency. It involves underwater communication and networking technologies in support of several applications related to safety in operational environment, including establishing and maintaining a safe operating area, forward reconnaissance, underwater surveying using multiple AUVs and general-purpose communications. These objectives will be achieved by special-purpose reconfigurable modem design and by developing protocols for underwater channel access, routing and error control. The outcome of the project will be demonstrated using a heterogeneous network of several nodes including 2 mobile AUVs. RACUN does not have a public web site, but its concept is described in a paper appeared at IEEE/OES OCEANS 2011 Santander. The paper can be downloaded here . |
Further efforts include collaborations with the IMDEA Networks Institute, the University of Haifa, the NATO STO CMRE and the Scripps Institution of Oceanography. Past collaborations with Scripps and WHOI were funded by the US NSF and ONR. A collaboration with JHUAPL and a collaboration with SPAWAR have also been also funded by ONR.
