Description

 IoT operation system and method for providing service to users This application claims to be submitted to the Chinese Patent Office on January 6, 2011, the application number is 201110001954.0, and the invention is entitled "Internet of Things Operation System and Methods of Providing Services to Users" Priority of the application, the entire contents of which are incorporated herein by reference. Say

Technical field

 The invention belongs to the field of network technology, and relates to an Internet of Things, in particular to an Internet of Things operating system and a distributed service method for providing services for Internet of Things users. Book

Background technique

 The Internet of Things refers to the collection of any information needed to monitor, connect, and interact with objects such as sound, light, heat, and location through sensors, RFID, GPS, etc., through various possible network accesses. Realize the ubiquitous linking of objects and objects, objects and people, and realize the intelligent perception, identification and management of goods and processes. With the continuous development of information technology, the third wave of the information world has arrived. The Internet of Things will play an important role in our production and life. What kind of operation mode the Internet of Things uses and how to provide services is the soul of the development of the Internet of Things. Where. One of the core concepts of the Internet of Things is to implement access to existing networks through ubiquitous terminals and facilities such as sensors, mobile terminals, industrial systems, building control systems, home smart facilities, video surveillance systems, etc. Better management to provide users with better service.

 The existing IoT service mode is shown in Figure 1. It is mainly through the establishment of the IoT service providing center to manage application servers such as personal home applications, enterprise industry applications and government public applications of the Internet of Things. The application server interacts with the underlying sensors, RFID (Radio Frequency Identification) and other networks through the communication network and the IoT gateway to provide services for users. The existing IoT service methods mainly have the following shortcomings: 1) The IoT service providing center faces a huge load, and the storage capacity and computing capacity cannot meet the application requirements. With the continuous development of information technology, the future Internet of Things industry is 30 times larger than the Internet. There is a need for new IoT service methods to share the load of the IoT service delivery center, thus providing high-quality services to IoT users.

2) High real-time applications face high latency. In the existing IoT service mode, all service providers must pass through the service delivery center, which will inevitably cause high latency. For example, users need to know the real-time traffic conditions in Area A. If the service delivery center is not in Area A, the road conditions monitored by related IoT devices. Information must be passed to the remote service delivery center After the processing is closed, it is provided to the user, and the real-time performance is relatively poor. If the relevant service providing center in Area A can directly process the road condition information and directly hand it to the user after processing, the real-time performance will be greatly improved.

 3) Poor scalability, and the information monitored by cognitive networks such as WSN (Wireless Sensor Network), RFID and ZigBee cannot provide services for traditional applications. With the continuous development of information technology, more and more traditional applications need to use the information monitored by the network to provide users with high-quality services. In the existing IoT service mode, the monitoring information of the network cannot be provided to traditional applications. Summary of the invention
