Internet of things system framework based on content center network

Abstract

The invention provides an Internet of things system framework based on a content center network. By using the Internet of things, all the objects in the world actively carry out information exchange through the Internet so as to realize interconnection of any objects at any moments and any places, a ubiquitous network and ubiquitous computing. Currently, there are 25 billions of devices which are connected to the Internet of things. The devices are intelligent and a lot of data is generated so that an extensible information center network is required. A large amount of data collection and distribution of the Internet of things only concern content data itself instead of an address of content storage, which is the same with the current Internet. In the invention, the content center network which is designed for a future Internet is introduced into the Internet of things. Aiming at differences of the Internet of things and the Internet, lots of resource-constrained devices, a lot of small data transmission, coexistence of various kinds of communication modes and diversification of flow types, a layered Internet of things system framework based on the content center network is provided.

Description

technical field [0001] The invention relates to an Internet of Things architecture based on a content-centric network, and the technical field of future network architecture applications. Background technique [0002] With the formulation of the "13th Five-Year Plan" for smart city construction, the demand for large-scale Internet of Things technology applications is even stronger. In order to realize the construction of large-scale Internet of Things, a scalable, flexible network architecture suitable for low-power networks has attracted the attention of the industry and academia, and has become the focus of Internet of Things technology research. [0003] In the Internet of Things, a huge number, a wide variety of low-power, small-volume sensors and other IoT sensing units such as radio frequency identification (RFID), two-dimensional codes, various terminals with built-in mobile communication modules, etc. The networked terminal network - the sensor network, opens up a w...

Problems solved by technology

[0004] At present, the network communication protocol of the Internet of Things adopts 6LowPAN / IPv6 / RPL (IPv6 for low-power wireless LAN and low-power lossy network routing protocol) similar to the structure of the Internet TCP / IP protocol (Transmission Control Protocol / Internet Internet Protocol). , to solve the sensor's requirements for low energy consumption, and realize the connection between the wireless sensor network and the Internet and the interconnection and interoperability between equipment from different manufacturers. 6LowPAN / IPv6 / RPL has promoted short-distance, low-speed, The development of low-power wireless personal area network, but because the payload that the protocol can carry is very limited, and consumes more computing and storage resources of smart devices, it is not suitable for the current and future high heterogeneity and large-scale Internet of Things
