Abstract
The Internet of Things is perceived today as a key opportunity for commercial development in different sectors of activity. Ehealth is a new IoT ecosystem where several microcomputer with health detection capabilities can diagnose the state of health of a patient, to deduce if his condition is stable or if a need for medical intervention very fast is obligatory, to prevent against any threat that can make us lose our patient. Our work consist of connecting three Ehealth microcomputers, each one relayed to ten health sensors and an alert button, to collect the health information of three different patients in movement, and send it to the medical server in the Internet for decision making, using an UTMS network in the network access layer, andtheATMnetworkinthecorelayer.ThesimulationofourIoT Ehealth Ecosystem is done using the riverbed modeler academic edition 17.5, and lasts for 60 minutes, the performance study is done in the physical and data link layers, in the application layer in case of using a Voice and HTTP applications.
