CONSTRAINED RELAY NODE DEPLOYMENT FOR UNDERWATER ACOUSTIC WIRELESS SENSOR NETWORKS

Discrete Mathematics, Algorithms and Applications, 2012
An underwater acoustic wireless sensor network (UA-WSN) consists of many resource-constrained underwater sensor nodes (USNs), which are deployed to perform collaborative monitoring tasks over a given region. One way to preserve network connectivity while guaranteeing other network QoS is to deploy some relay nodes (RNs) in the networks.

Design Considerations for an Environmental Monitoring Wireless Acoustic Sensor Network

Sensor Letters, 2015
A wireless acoustic sensor network for the sound/acoustic monitoring of areas of environmental interest, and the automated generation of multi-level sound maps for environmental assessment has been recently proposed. This contribution focuses on the design considerations of such a network, and especially on the relation of specific performance factors,

Characterization of acoustic channel for underwater wireless sensor networks

2015 Annual IEEE India Conference (INDICON), 2015
The paper presents an analysis of variation in attenuation, transmission loss and power spectral density of noise with respect to the change in the frequency of acoustic signals in underwater wireless sensor networks. The effects have been shown by considering the factors like depth, temperature and salinity of sea for calculating the propagation speed
