Design and Realization of Personal IoT Architecture Based on Mobile Gateway

In IoT, connectivity for local and/or wide area is fundamental to collect sensed data from IoT field devices or to send control information to the devices. Up to now, most of IoT devices equip still personal area level wireless radio interfaces due to cost of radio modules, energy consumption, and subscription requirement of wireless cellular networks such as 3G, WiMAX and LTE. In order to collect data from such devices possibly moving in the Internet, a gateway or relay node that can transfers the data using wide area communication techniques is necessary. A smartphone which provide a tethering function can play a role of the gateway for personal IoT environment and it does not require additional subscription for personal IoT devices and provides location independent connectivity. In this paper, we design personal IoT architecture based on mobile gateway and realize it with two case studies, remote control of car navigation system and home automation examples.
