The Internet of Things (IoT) uses communication technologies such as local networks or the Internet to connect sensors, controllers, machines, people, and objects in a new way, forming a connection between people and things, things and things, and realizing informationization and remote management control. Intelligent network. It is an important part of the new generation of information technology and an important stage of development in the information age.
After rapid development in recent years, the concept of the Internet of Things is now very hot. The Internet of Things laboratory in the 1970s can only be a star network structure based on a mobile terminal such as a mobile phone. In the 2.0s, the Internet of Things is now Beginning to cross the object, the interconnection between any items will be completed. The following will analyze some of the protocol structures and processing plans of the Internet of Things from the perspective of skills, and see how the concept of the Internet of Things can be completed through these skills.
According to the prediction of the Internet data base, by 2020, the Internet of Things will have an interconnection of 210 billion items, and consumers' experience will continue to improve along with the development of Internet of Things skills. However, to ensure the concept of the interconnection of objects, the relevant agreements, norms, structures and treatment plans are indispensable, and they can be divided into three categories based on different channels and commodities:
The first category is the IoT solution skills processing plan provided to address detailed questions. The plan is related to a detailed agreement, such as Zero Conf, the full name of Zero configuraTIon networking, which is a skill for automatically generating available IP addresses. It does not require a nominal manual configuration and a dedicated configuration server, making it easy for non-professional users. Connect with all kinds of network equipment, such as computers and printers. All the processes of establishing the network are automated through the process. This type of processing plan is based on a detailed implementation plan to make resolutions. It takes a long time, the products are different, and the selection is not the same.
The second category is to create a structure for multiple protocols. This structure handles detailed interoperability questions, with a focus on including multiple data paths, and can handle multiple questions including security, commodity commissioning, and route selection. For example, the AllSeen Alliance is a typical representative of this category. It is an IoT alliance consisting of dozens of companies including Qualcomm, Haier, Linux Foundation, TP-Link and Cisco. It includes processor vendors and network infrastructure. Various companies such as providers, router vendors and home terminal manufacturers. This alliance is mainly driven by Qualcomm's original base. The structure is derived from the AllJoyn open source project. Whether it is a terminal product or a service, AllJoyn can complete mutual communication.
The third category is a plan for detailed use. For example, the Home Internet of Things Protocol Thread is a typical representative of this category. It is committed to securely and reliably connecting hundreds of products in the home to ensure the stability of the battery life. Thread is jointly launched by companies such as Samsung, Freescale and ARM. It is an IP-based wireless network protocol. Nowadays, the network protocols commonly used in our homes have different defects. For example, although Bluetooth power consumption is low, IPv6 is not supported, and 2.0 and 4.0 present a situation of disordered coexistence; Wifi is suitable for transmitting a lot of data, but power consumption is yet High; ZigBee wiring is messy and not suitable for home users. Thread makes up for these shortcomings. After 6LoWPAN skills support IPv6, it can support more than 250 devices to network together, which can cover all the lamps, switches, sensors and other smart devices in the home, ensuring that the ultra-low energy can also make the device together. Safe operation for several years.
These protocol structures and processing plans are all based on the detailed needs of the professional IoT school. All developments are based on the guidelines of simplifying the connection and optimizing user experience, and laying a solid foundation for the completion of the detailed skills of the Internet of Things. basis.
To build a very good IoT, connect billions of devices, and let users participate, it is the real key to combine all these protocol structures and processing plans through IoT channels. Nowadays, the Internet of Things cloud channel can now handle the problem of device connection and data transmission, but the structure is not so sophisticated. After the structure is recognized by the industry chain, the large channel of the Internet of Things will be more perfect. Here, let's wait, a IoT channel that combines protocols, structures, and usage plans will be available in the near future.
