Welcome to WUWNet 2009, the Fourth ACM International Workshop on UnderWater Networks! Underwater networking promises to open exciting new frontiers for scientific, environmental, commercial, safety and military applications. Indeed, rivers, oceans and lakes occupy a central place in the world, and our impact on them is profound. However, networked underwater systems face many obstacles. The environment is harsh both as a communications medium and as a physical environment in which to deploy and maintain equipment. While the challenges are significant, they also present great opportunities for exciting new research and development with a potentially large impact.
Since 2006, WUWNet has been a strong venue for underwater networking research, from the physical layer to applications. WUWNet has traditionally had a strong showing of communications and networking papers. This year the PC chairs, in consultation with the general chairs and steering committee, sought to broaden WUWNet to include involvement of researchers in underwater robotics and applications. With the help of the program committee and authors we are happy to present 9 full papers, 4 short papers, and 3 posters that showcase research work in this developing field. We thank the 12 program committee members and 24 reviewers for their hard work in helping to select the papers. Of the 30 papers submitted to the workshop, all received at least three reviews, and several four or five as different PC members weighed in. Two-thirds of the papers were discussed at the program committee teleconference, and from this body 9 were recommended for full length papers, 4 for short papers, and 3 for posters. We are also delighted to include an invited speaker, Professor Robert F. Chen from the University of Massachusetts Boston, who is a project leader at the Center for Coastal Environmental Sensing Networks (CESN).

Symbol by symbol Doppler rate estimation for highly mobile underwater OFDM
We propose an OFDM receiver capable of estimating and correcting, on a symbol-by-symbol basis, the subcarrier dependent Doppler shifting due to the movement of source and receiver in an underwater acoustic network. We propose two methods of estimation: ...
Implementation of an embedded sensor network for the coordination of Slocum gliders for coastal monitoring and observation
Autonomous Underwater Vehicles (AUVs) are revolutionizing oceanography through their versatility, autonomy and endurance. However, they are still an underutilized technology. For coastal operations, the ability to track a certain feature is of interest ...
On efficient channel estimation for underwater acoustic OFDM systems
Channel estimation algorithms for Orthogonal Frequency Division Multiplexing (OFDM) employed in underwater acoustic (UWA) channels are investigated. Due to the slow propagation speed of acoustic waves, the compression and dilation effect on the time ...
World ocean simulation system (WOSS): a simulation tool for underwater networks with realistic propagation modeling
Network simulators are a fundamental tool for the performance evaluation of protocols and applications in complex scenarios, which would be too expensive or infeasible to realize in practice.
With the aim to provide a shared environment for the ...
Collaborative tracking in mobile underwater networks
A key requirement of underwater sensing systems is to track the position of devices while submerged. Traditionally, such tracking has relied on inertial navigation units and acoustic range measurements with surface beacons to estimate node positions ...
Capacity bounds and power allocation for underwater acoustic relay channels with ISI
Underwater acoustics channels suffer from a variety of effects including frequency selective fading, range dependent effective bandwidth and time-variation[1]. Herein, throughput capacity bounds and associated power allocation schemes for an underwater ...
Software-defined underwater acoustic networking platform
Currently acoustics is the primary modality for underwater communication even though it presents a difficult channel. To try and cope with the challenges of the channel many MAC protocols and PHY layer techniques have been proposed. In this paper we ...
Wireless sensor networks in coastal marine environments: a study case outcome
In this paper the results of an experimental wireless sensor network application in a coastal shallow water marine environment are presented. The study focuses on the practical aspects of deployment, data gathering and retrieval events. The trial sensor ...
Electromagnetic wave wireless communication in shallow water coastal environment: theoretical analysis and experimental results
Shallow water coastal environments are very important from the biological, social and economic point of view. Wireless technologies - and in particular wireless sensor networks (WSN) - are critical for enabling their efficient and pervasive monitoring. ...
Token-based data collection protocols for multi-hop underwater acoustic sensor networks: short paper
We propose two novel token-based data collection protocols for multi-hop underwater acoustic sensor networks (UW-ASNs). The proposed protocols, namely the tree-based protocol and the ring-based protocol, use tokens to guarantee contention-free medium ...
Low-cost medium-range optical underwater modem: short paper
Enhancing underwater instruments with networking capabilities is opening up exciting new opportunities for remote ocean exploration. Underwater communication is essential in enabling networking, and in this work, we focus specifically on those ...
The softwater modem: a software modem for underwater acoustic communication: short paper
The Softwater Modem is a software modem for underwater acoustic communication that enables users to run applications on the familiar sockets interface without any additional hardware except for transducers and associated amplification. A standard TCP or ...
Performance analysis of a MACA based protocol for adhoc underwater networks: short paper
This paper presents novel performance analysis of a MACA-based MAC protocol for underwater networks. MACA is very popular in terrestrial radio networks (such as 802.11) and many papers have presented its performance analysis. However, previously ...
Minimizing localization cost with mobile anchor in underwater sensor networks: extended abstract
In underwater sensor networks (UWSNs), it is important to know the position of each sensor node to identify the place of event in the target ocean field. Ling et al. proposed a localization method that estimates the positions of sensor nodes based on ...
Tradeoffs and design choices for a software defined acoustic modem: a case study: extended abstract
Challenges in developing high performance underwater acoustic modems can be summarized as:
1. Lack of maturity in underwater acoustic communications technology at all layers of the communication stack. This stems in part from the complex and dynamic ...
A toolchain for rapid prototyping of underwater communication systems: extended abstract
This paper introduces the RaPTEX toolchain and its use for the rapid prototyping and evaluation of an underwater ultrasonic communication system. The main goal of our RaPTEX toolchain is to bridge this gap between the need for embedded communication ...
