Acoustic source localization in noisy wireless sensor networks
IET 2nd International Conference on Wireless, Mobile and Multimedia Networks (ICWMMN 2008), 2008Target localization is one of the typical applications of wireless sensor networks. However, there are few localization algorithms addressing the problems caused by both the noisy wireless channels and the limited sensing range and energy of sensor nodes.

Acoustic localization based on wireless sensor network
2014Wireless Sensor Networks (WSN) has recently become tremendous application and research area. Accordingly, localization issue of WSN is becoming a hot topic, which aims to recognize the position of concerned object. However, it is well known that WSN is quite complicated in a real environment due to the characteristic of ad-hoc network and also limited ...

Sensor Selection and Rate Distribution Based Beamforming in Wireless Acoustic Sensor Networks
2019 27th European Signal Processing Conference (EUSIPCO), 2019Power usage is an important aspect of wireless acoustic sensor networks (WASNs) and reducing the amount of information that is to be transmitted is one effective way to save it. In previous contributions, we presented sensor selection as well as rate distribution methods to reduce the power usage of beamforming algorithms in WASNs.

Acoustic Source Positioning based on Sensor Selection in Wireless Sensor Network
2020 3rd International Conference on Algorithms, Computing and Artificial Intelligence, 2020Since the bandwidth and energy of wireless sensor networks (WSNs) are limited, it is not appropriate to use all the sensors for acoustic source positioning and so the need for sensor selection. In the article, an efficient expectation maximization algorithm based on sensor selection (EM-SS) is proposed for acoustic source positioning in the WSNs.

Acoustic Target Localization Algorithm in Wireless Sensor Networks
2013Self-organizing and high fault tolerant characteristics of wireless sensor networks make them have great advantages in target tracking region, but untagged target localization is always a difficult problem to be solved. When the target appeared in the detection region, it must cause the nearby environment parameter change.

CONSTRAINED RELAY NODE DEPLOYMENT FOR UNDERWATER ACOUSTIC WIRELESS SENSOR NETWORKS
Discrete Mathematics, Algorithms and Applications, 2012An 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.
