Recent Advances of Patient Monitoring in Internet of Healthcare Things : A Comparative Study

Healthcare requires the cooperation of many administrative units and medical specialties. The Internet of Things (IoT) is involved into healthcare field and plays an extremely important role by providing healthcare services. In the Internet of Healthcare Things (IoHT) several challenges appeared in terms of limited battery life, long processing time, large amounts of collected data, paquets overhead on sink,…etc. A lot of research studies have been done in order to improve the healthcare IoT based applications. However, these proposed systems have been focused on some specific purpose without ensuring an effective solution for all problems. This paper presents a comparative study for the recent advances in Internet of healthcare monitoring. In addition, an optimized intra WBSN communication (OIC) an is proposed in order to overcome the over-mentioned challenges. OIC is based on merging an energy efficient routing protocol with the data transmission process. This approach also reduces the data acquisition redundancy, and finds the optimum path for data transmission, according to the patient situation. Our approach is implemented and tested on real biosensor data while the obtained results prove the efficiency on extending the network lifetime (up to 84%), removing the data transmission redundancy (up to 60%), minimizing the overhead on sink (up to 83%), and optimizing the transmission time. Based on a comparative study with four state-of-the-art methods, the superiority of our approach is validated.
