Abstract: This paper presents the development and results of a mobile sensor based opportunistic urban pollution monitoring network that uses public transportation buses as platforms for its deployment. This work is an extended and improved version of the paper presented to the IDAACS’09 conference. It reports some aspects of the implementation of a single pollution sensor based sensing node prototype which was used for testing an opportunistic communications network and which was reported in depth elsewhere. More emphasis is given to the description of the basic sensing unit and its modular conversion into a sensing system able to acquire data on several pollutants as well as temperature, humidity and geo-location information. The software architecture developed around it in order to process the huge amounts of data the system produces is also described. The different prototypes were tested on the public transportation system of the city of Vigo and on multiple test runs around the city of A Coruña in the north-west of Spain producing very promising results.

Keywords: Pollution monitoring, Opportunistic sensor networks, Mobile sensor networks
