The growth in wireless services indicates the importance of wireless networks. Parameters in domains Specific Wireless Sensor Network (WSN) based applications such as infrastructure, physiological and activity monitoring are using the wireless services. Inactivity monitoring, the home care and hospital care Wireless IoT sensors devices continuously monitor and collect data. So, these devices consume lots of energy. With secure data transmission, the limited energy supply is the central issue in-home care and hospital care applications. This research focuses on restricted-energy utilization while monitoring users' postural activity information in homecare and hospital-care applications using IoT-based WSN devices (sensors). In this research, the Rank Based Energy Efficient key management (RBE-EKM) protocol is designed to discover an energy-efficient approach to transfer the sensor's data to the Base Station (BS). Initially, it assigns higher priority to the sensor nodes based on their emergency interrupt signals, and the shared key is allocated foremost to those prioritized nodes. This ranking key method establishes the secure routing path for these sensor nodes by verifying their shared secret key. The shared key-based security scheme is found in this research to prevent the WSN from node compromising attacks. The simulation analysis of the RBE-EKM protocol model shows that real-time data is successfully shared among the group of privileged Base Stations with minimum power consumption, delay, and throughput. Moreover, the experimental result proves that the proposed communication strategy, such as dynamic retransmit or rebroadcast decision control, significantly improves the performance of AODV protocol models. |
