“…This technique is suitable for transferring small data over short distances [15]. This technology transmits information to all the surrounding devices by releasing waves through the beacons [16]. Accordingly, it can be said that the information is being broadcasted by Beacons, and a device near the Beacons broadcast that information again.…”

Wireless sensor networks are becoming popular in health-care systems day by day with the rapid growth of new technologies and application, including Location-based aware systems. Following the comprehensive health-care reforms in past years, it motivates researchers to improve approachability to health-care specially in hospitals and health centers. The main purpose of this research is to develop a model for using of Location-based systems through iBeacon and Bluetooth Low Energy technologies in health-care. The proposed model is developed for hospitals as one of the active places, where time is critical. One of the major problems in the hospital environment is often the waiting time, procedures and finding appropriate departments, which are because of large population and the size of a hospital. To endeavor this dilemma, we developed a model that easily can help for the centers and places to visited by patients through their smartphone devices and examine it in a real indoor environment. The results show that, the proposed model can significantly improve hospital information management and patient guidance, and keep them up-to-date and provide detailed patient database, patient's information and location to keep them track of doctor's appointment, and receiving a medication. With using different sensors, BLS, iBeacon and BLE, we can align patient, doctor, nurse, and pharmacy vendor to the specific purpose of satisfying patient's needs.
