Rate-Distributed Spatial Filtering Based Noise Reduction in Wireless Acoustic Sensor Networks
In wireless acoustic sensor networks (WASNs), sensors typically have a limited energy budget as they are often battery driven. Energy efficiency is therefore essential to the design of algorithms in WASNs. One way to reduce energy costs is to only select the sensors which are most informative, a problem known as sensor selection. In this way, only sensors that significantly contribute to the ta...
متن کاملNoise Mitigation for Target Tracking in Wireless Acoustic Sensor Networks
In wireless sensor network (WSN) environments, environmental noises are generated by, for example, small passing animals, crickets chirping or foliage blowing and will interfere target detection if the noises are higher than the sensor threshold value. For accurate tracking by acoustic WSNs, these environmental noises should be filtered out before initiating track. This paper presents the effec...
متن کاملAcoustic Ranging in Resource-Constrained Sensor Networks
Fine-grained geographic localization of nodes is essential for an extensive range of distributed sensor applications. To compute geographic coordinates, localization algorithms commonly use pair-wise distance estimates between nodes. In this paper we present a noise tolerant acoustic ranging mechanism for wireless sensors that employs digital signal processing techniques on standard MICA hardwa...
متن کاملA Fuzzy Based Approach for Rate Control in Wireless Multimedia Sensor Networks
Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...
متن کاملAcoustic Communication in Wireless Sensor Networks
Acoustic communication has been widely used in undersea wireless networks. In this paper, we explore the use of acoustic communication in terrestrial wireless sensor networks. This work does not aim to replace the radio communication which is widely used in wireless sensor networks. Rather, we aim to provide an alternative way of communication among the motes in case that the radio transceiver ...
