Indoor Location Monitoring and Navigation System for Hospitals

As large buildings, hospitals offer many situations where patients can get lost or medical personnel has trouble locating a patient inside a hospital or around its premises. Lost patients can lead to increased cost from wasting hospital employee time but more importantly to situations that can be dangerous or life threatening for some patients. The paper studies the use of a ZigBee network for patient location detection as well as indoor navigation within a hospital building. The system employs hospital mapping based on graph theory, a distinct three-technology network and a patient device that both measures the patient temperature and is also part of the location subsystem. The system obtained has lower power consumption and an average cost lower than other similar solutions.
