Acoustic noise pollution monitoring in an urban environment using a VANET network

Abstract

International audienceThe main objective of this work is the development of a Vehicle Ad Hoc NETwork (VANET) to collect data from GPS equipped mobile phones used as noise detectors. In this system, sensor nodes perioadically transmit acoustic noise levels to neighboring cars, data packets being shared and temporary stored by participating VANET nodes and ultimately forwarded to a collector node connected to the Internet, providing public real-time data. A routing technique called MP-OLSR that takes into account the spatially separation between the multiple paths is used, for better transmission reliability and congestion avoidance as well as for control message overhead minimization

Recuperação e Monitoramento de Dados Utilizando a Rede de Transporte Público

“…Os trabalhos seguintes possuem similaridades com o trabalho proposto no que diz respeitoà questões de monitoramento em ambientes urbanos eà construção de redes DTN utilizando informações GPS de veículos. Em [Radu et al 2012], os autores propõem o desenvolvimento de uma rede veicular ad-hoc com o objetivo de coletar dados de telefones celulares equipados com GPS e utilizados como detectores de ruído. Os autores propõem uma solução de roteamento para os dados disseminados através da VA-NET utilizando o protocolo MP-OLSR, uma modificação do protocolo OLSR que faz uso de múltiplos caminhos para realizar o encaminhamento dos pacotes, apresentando uma melhor taxa de entrega e menor atraso quando comparado ao protocolo original.…”

APHONIC: Adaptive thresholding for noise cancellation in smart mobile environments

“…We observe a mixture of the desired speech signal and ambient noise, on a mobile device. Prior information could be made available on a peer-to-peer basis, similar in spirit to the manner in which resources are shared by intelligent messaging frameworks [3], or by leveraging measurements from acoustic noise pollution monitoring systems in urban environments [4]. For example, in a Mobile Cloud Computing (MCC) scenario, energy-efficient stochastic leader-selection algorithms may be used by mobile handsets to determine which sensor should supply the prior information [5].…”

Evaluation of Noise Level: Experimental Case Study for Some External Arenas in the University of Technology at Baghdad

“…Important political issues in many countries such as the European Commission are interested to avoidance, prevention and reduction of the harmful effects of exposure to environmental noise. Public parks, quiet urban areas, quiet area in the open country, areas near schools, hospitals and other sensitive buildings are taken into consideration in the development of the Vehicle Ad Hoc Network (VANET) to collect data from GPS equipped mobile phones [10]. Noising map can be used to show the distribution of noise signal levels in the real time by monitor the noise pollution situation of cites environment [11].…”
