Survey on Improving Energy Efficiency and Security in IoT Wearable Devices for Data Collection and Classification

In this survey, the authors collected the Internet of Things (IoT) and Wireless Sensor Networks (WSN) oriented wearable sensor devices, energy efficiency and avoiding attacks. IoT wearable sensors are fitness trackers and smart- watches. Healthcare, activity recognition and individualized monitoring are few of the potential uses for the wearable IoT devices which continuously collect the data on motion, health and environmental interactions. Optimizing the energy efficiency and decreasing end-to-end latency in WSNs by the distributed clustering and energy cost functions in routing. Balancing the latency, energy cost and reliability, the multi- path routing improves. Wormhole attacks in Wireless Sensor Networks (WSNs) are difficult in detection due to their use of hidden channels. Despite the security measures like authentication and encryption, these attacks are combined with the others to become a significant threat.
