- Abstract
- IoT devices such as smart watches and smart bands are used in an IoT environment to provide healthcare services. These IoT devices measure users' continuous movement and transmit the results through the network. However, if the IoT device is out of the network range, continuous services are interrupted. In addition, it is difficult to monitor and control a large number of IoT devices connected to the network with only a single integrated management server. Therefore, in this study, we propose a smart model for mobility management of IoT devices by defining a smart gateway to manage IoT device connection to the network. In this model, we also designed and implemented a protocol for mobility management between Smart gateway and IoT device. Finally, comparison of handover delay time with existing mobility management protocols confirmed that the delay time was approximately halved. We additionally measured the request/response time according to the distance between the smart gateway and the mobile IoT device. This confirmed the effectiveness of the IoT device mobility management method using the proposed protocol, which is about 80 ms faster than the existing protocol.
