CIRELA (Communication and Information technology for REsiLience to disAsters) is a non profit NGO aiming at providing open source solutions to manage, monitor and prevent natural and environmental disasters. Currently we are focusing on wireless sensor network (WSN) based monitoring and warning systems.

We are working on WSN applications where people in a disaster-prone area can actively participate, to have access to information, to be warned on time, and to have their own sensor if they want. Jakarta with frequent flood events is currently a case we are working on.

A 'simple' WSN based flood monitoring application will measure water levels on different locations using sensors, put this information on a server and make it available to users, warn people when the water level in an area is higher than an acceptable limit, ... So we have to manage a geographically distributed and concurrent system where sensor modules represent concurrent processes.

We want to have a pleasant and user friendly environment for end-users as well as for programmers. We started to develop our applications with Pharo. We'll show Pharo with OpenStreetMap and Roassal2: - to visualize geographic data and information - to present and to simulate wireless sensor networks
