Description

A kind of programmable framework of Internet of Things

Technical field

The present invention relates to communication network field, more particularly to queueing theory, and optimum theory.

Background technology

Internet of Things (The Internet of Things, IOT), both " the Internet that thing thing is connected ".At present, with regard to Internet of Things Net more accurately defines:Internet of Things is by various awareness apparatus and system, bar code and Quick Response Code, global positioning system, According to the communication protocol of agreement, thing is coupled together with thing, people and thing, person to person, by networks such as various access networks, the Internets Enter row information to exchange, to realize a kind of information network of Weigh sensor, positioning, tracking, monitoring and management, in this network In, each object can address, and each object can control, and each object can communicate.

There is essential distinction in Internet of Things and traditional the Internet, the difference of the two is:First, Internet of Things is complete to having The object of face perception and the interconnected set of people, the purpose of Internet of Things complete perception is to enter row information to object whenever and wherever possible to adopt Collection and acquisition, the technological means of employing mainly have RFID technique, planar bar code technology, GPS technology, sensor technology, wireless sensing Device network etc..As the integrated application of various cognition technologies, its application process needs polytype sensor to Internet of Things, these Different information can be captured and there is the sensor of different information formats all as different information sources, gather institute according to certain rules The information needing, and the data that sensor uploads has real-time；Secondly, Internet of Things has reliable transfer capability to data, Number of sensors on Internet of Things is extremely huge, defines the collection information of magnanimity, it is various that this requires that Internet of Things must adapt to , to guarantee the correctness of data and promptness in transmitting procedure, Internet of Things is a kind of foundation on the internet for heterogeneous network and agreement Network, as the extension of the Internet, Internet of Things follows the communication protocol of agreement, realizes the logical of regulation by corresponding software and hardware Letter rule, the object information collecting accurately is passed by various wired and wireless network and the Internet converged in real time； Finally, Internet of Things is capable of Intelligent treatment, and Intelligent treatment can be described as Internet of Things core the most and crucial part, is also thing The basis that networking can be used widely, it can compare the technology in forward position by the current every subjects of integrated application, to oneself through warp Cross sensing layer complete perception and the data of transport layer reliability error free transport is comprehensively analyzed and processed, be that people are currently engaged in Various activities make guidance, this guidance is forward-looking, and typically intelligentized, and in Internet of Things, not only carries Supply the connection of sensor and the various networks such as the Internet, Internet of Things itself can also carry out Intelligent treatment, had real to object Apply the ability of Based Intelligent Control.Sensor technology and Intelligent treatment technology are blended by Internet of Things, in conjunction with cloud computing, pattern recognition etc. Various intellectual technologies, expand its application, and Internet of Things typical architecture is as shown in Figure 1.

The sensing layer of Internet of Things is the basis of Internet of Things development and application, and the function of this layer is to carry out thing using sensor The collection of reason world information.This layer of most commonly used technology have REID, sensing technology, remote operation technology and ZigBee technology etc..Object itself does not possess communication capacity, and sensing layer sensor and RFID technique enter rower to various objects Know, by the communication module of the sublayer of communication such as short-distance wireless communication technology and gateway interactive information.Sensing layer equipment has many Kind extend net, includings Sensor Network, Wireless Personal Network (WPAN), home network, industrial bus etc. it is also possible to first composition extension net again with Gateway interacts.

The Internet of Internet of Things is set up on existing mobile radio communication and Internet basic, the Main Function of Internet it One is using the various types of networks that can be connected into the Internet, and data and control instruction are carried out safe and reliable, accurate and effective Transmission, realize the communication of algorithms in data transmission procedure simultaneously.It is also thing that the data that sensing layer is uploaded carries out storing analysis The important component part of intranet network layer, is the basis of the numerous application of application layer.

Therefore, for lifting the transmission efficiency of Internet of Things, a kind of flexible information transfer framework need to be designed, realize the height of business Effect scheduling.

Content of the invention

The technical problem to be solved is：By setting up programmable resource management framework and Internet of Things optimal transmission Path, realizes the flexible resource management of Internet of Things, and the programmable framework of Internet of Things is as shown in Figure 2.

The present invention comprises the following steps by solving the technical scheme that above-mentioned technical problem is adopted：
