SRT Synchronization Protocol for Healthcare IoT

Abstract

there is a lot of development in Sensor networks for healthcare IoT in recent years. For health care monitoring and proper medication sensors are attached to human bodies.  Body sensors require accurate time synchronization in order to monitor health conditions. and medication usage. Nodes life time decreases due to in adequate power supply. This influences the efficiency and robustness of time synchronization protocols. The time synchronization process cannot be completed if a root node fails. To solve this problem, we present a Self-Recoverable Time Synchronization (SRTS) scheme for healthcare IoT. Here a recovery timer is set up for candidate nodes, which are dynamically elected. The candidate node whose timer expires first takes charge of selecting a new root node.
