Smarp: A Stochastic Mac Protocol With Randomized Power Control For Underwater Sensor Networks10/10/2021
Some of the output could be proposed as standards as a much desired network standard does not exist today.PUBLICATIONS PRODUCED AS A RESULT OF THIS RESEARCHWhen clicking on a Digital Object Identifier (DOI) number, you will be taken to an external site maintained by the publisher. Important discoveries can be expected in the area of innovative communications networks able to operate under the challenging conditions of underwater communications. Many other science disciplines will be able to take advantage of the type of data exchange with this instrument, including environmental sciences dealing with natural and human caused catastrophes.
Smarp: A Stochastic Protocol With Randomized Power Control For Underwater Sensor Networks Software For RemoteThrough results obtained by using the instrument. These publications made this project known to a large community of researchers and practitioners.5) A female graduate student earned her Ph.D. The buoy has the following characteristics: Rechargeable batteries (for the attached modem or other underwater assets) provision for energy harvesting (solar) on-board computational capabilities to facilitate (re)programmability and implementation of various networking protocols multiple wireless communication capabilities to communicate with the user on shore and allow real-time, remote control of all underwater assets.3) Deployment and testing of the NU MONET system in an indoor tank, in an outdoor tank, and in the ocean, at the Northeastern University Marine Science Center in Nahant, MA (a picture of the deployment in the ocean is available).4) Publication of several papers at premier peer-reviewed international conferences and journals in the field of networking. By the end of the project duration, we obtained the following outcomes.1) Design of a network architecture comprised of (i) commercial acoustic modems (Teledyne Benthos SM-975), (ii) ?smart buoys? connected to each of the modems, allowing communication to/from underwater assets from/to a station on shore, (iii) control software for remote (re)programmability of the modems and other underwater equipment (e.g., sensors), and (iv) a suite of networking protocols including those for media access control (MAC) and data gathering.2) Design and construction ?from scratch? of the smart buoy connected to each deployed acoustic modem (via underwater cables). Their policies may differ from this site.The project ?MRI: Development of the Northeastern University Marine Observatory NETwork (NU MONET)? aimed at building an instrument (called ?the NU MONET?) enabling underwater networking in support of the two following endeavors: 1) Provide communication and data gathering capabilities for the research of marine scientists with a large array of interests, 2) provide a semi-permanent multi-hop wireless (acoustic) network to be used for testing protocols at all layers of the networking protocol stack.These events include the NU College of Engineering Research Fairs (in Fall 2016, 20), the NU Talks (a Northeastern?s version of the Ted Talks, led by undergraduates), and presentation at the Marine Science Center students at Nahant (including the participation of high school students).9) Research outcomes of this project were also featured on WIRED (November 2016) and on the blog of the Sierra Circuits (July 2018). It is worth mentioning that thanks to his involvement with the project, the student Andrew Tu has: Published a paper at a peer-reviewed IEEE conference (MTS/IEEE OCEANS 2016) published a paper in Embark, the peer-reviewed Northeastern's Undergraduate Engineering Research Journal presented a poster on his work on the NU MONET Smart Buoy in Arlington, VA, at an REU-related event of the Council for Undergraduate Research, and traveled to Italy to collaborate on research with the underwater networking research group of professor Chiara Petrioli of the University of Rome ?La Sapienza.?8) The NU MONET team was present at several events geared towards fostering awareness of underwater communication and networking and their possibilities. Particularly, based on the lesson learned while designing, deploying and testing at sea of the NU MONET, the following classes were introduced in many communication and networking courses: (a) theory and practice of acoustic communication and related digital signal processing, (b) design and testing of protocols for channel access and data gathering in multi-hop wireless underwater networks, (c) network management and remote (re)programmability.7) Eight undergraduate students were supported through REU funding that supplemented this award. These protocols have been tested in water (indoor and outdoor settings) using the NU MONET.6) Education modules were produced for courses taught by the three PIs of the project.![]() ![]() ![]()
