Optimization of A Smart IOT Gateway

In recent years, the Internet of Things (IOT) has attracted many attentions. It allows a number of objects that have been embedded with wired or wireless communication interfaces to automatically communicate and interact with each other. The IOT is a system, combination of embedded controllers, sensors, software’s and network. After internet and mobile communication, IOT is regarded as the third wave of information because of its huge market prospects. The development of IOT can support a variety of applications including Intelligent Art, Intelligent Logistics, Intelligent Medicine & Healthcare, Intelligent Transportation, Intelligent Power, Smart Life etc. IOT Gateway plays an important role in IOT applications since it bridges between wireless sensor networks with traditional communication networks or internet. This paper includes an IOT Gateway system based on Zigbee and Wi-Fi protocols according to the presented data transmission between wireless sensor networks and mobile communication networks, typical IOT application scenarios and requirements from telecom operators, protocol conversion of different sensor network protocols, and control functionalities for sensor networks, and an implementation of prototyping system and system validation is given
