Continuous Displacement Plans Oriented Network

CoDPON networks are a specific DTN/Data Mule system inspired on the air traffic control system and proposed in ExtremeCom 2011. It is a new proposal aimed to make possible the technological inclusion in areas unprovided of communication infrastructure. The focus are amazonian scenarios where the fluvial mesh is the unique access to the exterior world environment.

Actually, the CoDPON project is a work in progress that is been development thanks to a partnership between the courses of Computer Science from Universities of Amazonia and Arizona.

Ultrasound Remote Exams (1)

A major difficulty in isolated areas like Marajó occurs due to the small number of physicians who reside in the region. The vast majority of those just make periodic visits.

Ultrasound Remote Exams (2) 

Among the most affected by this infrequency of medical attention in the communities are pregnant women, who need regular monitoring. One of the proposed applications is related to ultrasound examinations by health agents. The CoDPON system will act as a Mule, carrying and deliveringthe filesto the State capital for the analysis by physicians.

Medical care related to scalping of Amazon Children

Paives is an acronym (in portuguese) which means  Program for Integrated Assistance for Scalped Victims
Medical care related to scalping of Amazon Children
Daily, lots of Amazon dwellers  use little boats as the main means of transportation. Children usually go to school in these little motorized boats. Women and girls in these communities habitually grow their hair long and leave it untied.
Medical care related to scalping of Amazon Children
Most of the boats, used by riverine families, are built in a rudimentary and craft form, exposing the shaft which rotates the propeller engine. Accidents occur when the hair, especially of women, gets stuck in the uncovered shaft of the engine,  and due to mechanical strength of this revolving motion, is pulled causing the hair to be torn from the scalp.  
Social Reintegration related to scalping of Amazon Children
In this case we propose the use of CoDPON data mules to carry video, letters, pictures and another information from rural areas to urban areas (Santa Casa - the hospital where victims stay hosted for between 6 months and 1 year) and vice versa.
