Résumé:
The possibilities of new mobile distributed systems have
reached unprecedented levels. Such systems are dynamically composed of
networked resources in the environment, which may span from the immediate neighborhood of the users - as advocated by pervasive computing -
up to the entire globe - as envisioned by the Future Internet and one of
its major constituents, the Internet of Things. This paper more specifically concentrates on urban participatory mobile distributed systems
where people get involved in producing new knowledge about the urban
environment. Service-oriented and cloud computing are evident baseline
technologies for the target mobile distributed systems. Service orientation provides the abstraction to deal with the assembly of the relevant
heterogeneous component systems. The cloud provides the infrastructure
to deal with the gathering and analyses of the observations coming from
the sensing infrastructure, including from people. However, cloud-based
centralized solutions come at a price, regarding both resource consumption and privacy risk. Further, the high heterogeneity of the participating
nodes results in diverse levels of sensing accuracy. This paper provides
an overview of our past and ongoing research to overcome the challenges
facing urban participatory mobile distributed systems, which leverages
mobile collaborative sensing, networking and computing. The experience
with the Ambiciti platform and associated mobile app for monitoring the
individual and collective exposure to environmental pollution serves as
an illustrative use case.
