Real-Time Communication Support for Underwater Acoustic Sensor Networks

Real-Time Communication Support for Underwater Acoustic Sensor Networks †

Underwater sensor networks represent an important and promising field of research due to the large diversity of underwater ubiquitous applications that can be supported by these networks, e.g., systems that deliver tsunami and oil spill warnings, or monitor submarine ecosystems. Most of these monitoring and warning systems require real-time communication in wide area networks that have a low de...

A Secure Communication Suite for Underwater Acoustic Sensor Networks

In this paper we describe a security suite for Underwater Acoustic Sensor Networks comprising both fixed and mobile nodes. The security suite is composed of a secure routing protocol and a set of cryptographic primitives aimed at protecting the confidentiality and the integrity of underwater communication while taking into account the unique characteristics and constraints of the acoustic chann...

Efficient Communication Protocols for Underwater Acoustic Sensor Networks

An Ultrasonic Sensor Based Low-Power Acoustic Modem for Underwater Communication in Underwater Wireless Sensor Networks

Applications of underwater sensor networks involve environmental monitoring, disaster prevention, and resource detection. As the importance of these applications has recently grown, underwater sensor networks made up of sensor nodes have to be further investigated. However, little research has been performed to develop an underwater sensor node with communication functionality. In an underwater...

Energy Efficient and Reliable Communication in Underwater Acoustic Sensor Networks

Normally, the communication in the earth surface is through electromagnetic or radio waves. But this is not possible in the underwater environments in an efficient way. In underwater environments radio does not work well due to its quick attenuation in water. Hence the acoustic signals are sent using the acoustic channels. If the communication is done with retransmission, it gives rise to the p...
