Privacy Preserving Second-order Consensus for WASNs

open access: closed2018 37th Chinese Control Conference (CCC), 2018
Considering the privacy requirements on initial states for second-order consensus in wireless sensor and actuator networks (WSAN s), we focus on the design of one privacy-preserving second-order consensus (PPSC) protocol in a distributed way, and investigate this issue from both the viewpoints of limiting the kind of information to be broadcasted and ...

Sound event localization and classification using WASN in Outdoor Environment

open access: yesarXiv.org
Deep learning-based sound event localization and classification is an emerging research area within wireless acoustic sensor networks. However, current methods for sound event localization and classification typically rely on a single microphone array, making them susceptible to signal attenuation and environmental noise, which limits their monitoring ...

Optimization and Evaluation of an Energy-Efficient MAC Protocol for WASNs

open access: closed2010 Sixth International Conference on Networking and Services, 2010
A Wireless Ad hoc Sensor Network (WASN) is an autonomous collection of low cost devices that communicate over wireless links. This devices are often powered by limited energy resources, and it is expensive and sometimes infeasible to recharge or replace them. Hence, energy efficiency is the main design concern for such a network. In literature, several

An interference aware multi-channel MAC protocol for WASN

open access: closed2017 International Conference on Innovations in Electrical Engineering and Computational Technologies (ICIEECT), 2017
Wireless sensors network is a network consists of sensors node, creating cluster and selection of cluster head is an issue for an efficient WSN. A new technique is proposed in this research which is termed as Wireless Active Sensors Network (WASN). We designed a novel protocol called interference aware Multi channel protocol based on MAC for sensors ...

TDOA-Based Robust Sound Source Localization With Sparse Regularization in Wireless Acoustic Sensor Networks

IEEE/ACM Transactions on Audio Speech and Language Processing, 2022
Time difference of arrival (TDOA) measurements, which are contaminated by large values of error, known as outliers, would have a significant impact on the accuracy of sound source localization (SSL) in wireless acoustic sensor networks (WASNs).

Weighted Action-coupled Semantic Network (wASN) for robot intelligence

2008 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2008
Semantic knowledge especially for robots is often used as a form of knowledge representation which includes ontological knowledge to support description logics and rule language. However, it is difficult to design rules which provide some goal-associated context, object and space (COS)-action complexes to be used to infer alternative attempts for ...

The wheezer that wasn??t

Pediatric Emergency Care, 1992
The expression of cardiac dysfunction in pediatric patients with myocarditis may not be conspicuous. While older children with myocarditis may abruptly present with pleuritic or angina-like pain, infants and toddlers with fulminant disease are unable to verbalize such complaints.
