Wireless embedded devices, especially those of the open source hardware/software kind have seen rapid growth in recent years.
This kind of devices when combined with ad hoc networks and sensor data can be a low-cost and highly scalable solution to many applications.
In this paper we describe the experience of taking this concept of network infrastructure, developing application infrastructure and applying it, as a prototype, to a practical situation for a medium-sized city in the Buenos Aires province outer area, Argentina. We implement a novel sensor data delivery platform using open source hardware and software focused on streetlight maintenance at a fraction of the commercial implementation costs. To the extent of our knowledge this is the first system developed, deployed and documented in a Latin American country. Also presented in this paper is the system architecture as well as the design of hardware and software components as well as the results obtained.Sociedad Argentina de Informática e Investigación Operativ
