Abstract
Like other many fields, telemedicine has benefited from pervasive and ubiquitous access to knowledge granted by the internet and mobile wireless. Remote monitoring and diseases management are considered as most fasted growing areas within this field. Thanks to mobile communication technologies, humans today are able to provide patient with w better quality life in critical and emergency situations. In such a scenario, the patient needs to reach as soon as possible the health care provider and/or medical institution. To do so, he needs to go by a road without obstacles. In different research reviews, rooting algorithms that have been presented are treating the shortest path, the nearest path. In this paper, we present a new pervasive system able to find the Safe Area without mobile obstacles and impediments based on an incremental algorithm called Safe Region algorithm.
