  Air pollution is a major concern in large urban areas. Various studies have
been made to monitor and control the pollution level emitted by the vehicles
but some main factors like ease of implementation or feasibility of the
proposed approaches are not focused in the told studies. In this paper we
propose a wireless sensor network solution to monitor vehicles exhaust systems
pollution emission. Furthermore, we evaluate the feasibility of our proposed
approach with respect to energy consumption and network lifetime by means of
simulation. Our results indicate that our proposed scheme is practical for
implementation using well known MAC layer protocols.
