摘要：This paper proposes methods and tools to support analysis and simulation of propagation of
alerts in a city. Environmental modelling and monitoring is now a major framework for
application of wireless sensor networks. Sound and visual alerts remain a major way to warn
and prevent accidents in social life. This work combines a cellular segmentation of the city,
representation of buildings and roads, representation of vehicle paths and cell behaviour that
compute sound wave propagation with respect to space and time. As a First result, there is the
possibility to evaluate nuisance from vehicles repetitively travelling with sirens along
avenues. Coupling to smart cities sensing systems will allow a better control on trafic lights
and management of autonomous intersections. This can help to prevent and reduce noise and
accidents. In the context of smarts cities, cooperative sound detection can be associated to the
development of new smart cars, and better rescue or police vehicles. High speed simulations
with real time opportunities are obtained thanks to code generation for graphic accelerators.
