Revolutionary of secure lightweight energy efficient routing protocol for internet of medical things: a review

Advancements in the Internet of things (IoT) make a way for medical devices to coordinate in an environment that is the Internet of Medical Things (IoMT). In IoMT, some dedicated health monitoring devices are coordinated in an environment to accomplish a specified task. In this sector, patient information is periodically collected for early diagnosis of diseases. Various wearable sensors have been developed for smart sensing in the IoMT meanwhile, the sensed data are forwarded to the smart data collecting devices. Besides the advantages of remote monitoring and lower healthcare cost in IoT-based health monitoring systems, intrusion can occur during data transmission. Moreover, the large energy consumption of devices will result in higher system costs. An energy-efficient data routing protocol is developed in this area to cater to these issues. A swarm intelligence based approach is one of the most prominent methods for energy efficient routing of the data in IoT. The major goal of this paper is to provide deep insight into the lightweight, secure energy efficient routing protocol in IoMT. Furthermore, the limitations of existing methodologies are outlined.
