Abstract

Day after day we are facing with new challenges created by natural or man-made factors. In the first group we can mention earthquakes, heavy storms, earth slides etc, and in the second are wars that unfortunately are taking way people lives even though we live in 21st century. During and especially after every disaster the most difficult moments are to check for survivors under the ruins. In this work we propose a personal and easy to use device based in sensors technology that would make it possible to signal the presence of life signs from persons under the ruins such as pulse or oxygen level. The wireless network created from those devices would make it possible to transmit the signal even in long distances to reach the help emergency teams. To optimize the transmission distance and quality, we propose a new communication protocol for ad-hoc wireless networks. We can consider the network created by the sensors used for personal devices installed in patient wrists. The sensors communicate through a virtual infrastructure that helps to collect the data from the personal devices in an efficient way even in the areas affected by disasters where no wireless infrastructure can function. The communication scheme proposed here ensures a hierarchy of nodes that gives the possibility of saving by using simple devices for most of the population and more expensive and sophisticated ones only for the higher hierarchy rank nodes represented by prechosen individuals. For this reason, the protocol that we propose is a hierarchical protocol. The critical condition area, might be a city or village, is divided into virtual cells where each cell is represented from one main node that holds the communication for all the surrounded nodes and forwards its information towards the next cell main node found in the direction of the sink. This protocol gives the possibility to communicate even in the areas without any wireless infrastructure. The life signals collected from people leaving under ruins in the critical condition areas such as earthquakes, wars etc.
