Embedded Rule-based Management for Content-based DTNs
Several countries such as Uruguay and Brazil are implementing the well-known One Laptop Per Child Program (OLPC) by which every child that attend to primary school obtains in property a laptop with wireless capabilities. They carry their laptops from home to school and back every day and, as we observed in our research, they also carry their laptops to parks, community centers etc. That provides a wide platform for opportunistic, delay tolerant, networking applications. This paper presents a lowcost, delay-tolerant, network of sensors implemented embedding high-level decision-making capabilities inside consumer-grade wireless routers working together with the OLPC laptops. The sensors are deployed at the living premises of children in environmentally vulnerable neighborhoods as well as at their schools, parks, etc. The environmental data collected by the sensors is carried to the school by the laptops and from the school to monitoring stations over the Internet. In this system, all the entities in the network are publishers and subscribers of con_guration commands, policy-rules and environmental data, building a exible, self-management solution.
