Abstract

Internet of things is considered through monitoring, analysis and control of network information technology, the extension of human perception of control ability has huge potential. Iot research work has been carried out. A lot of Iot demonstration system was also developed, and has made remarkable application effect. But at the same time, the current development of the Internet of things is also facing some fundamental problems: the Internet of things has what special requirements must be met? What phase are you in the Internet of things technology? Where is the development direction of Internet of things? It is worthwhile to explore these issues. This paper reviews the development of the Internet, and according to the experience of the development of the Internet, analyzes the present situation of Internet of things and Internet of things present in the "content - machine connected to the local small-scale network stage, its development direction should be connected to open net of numerous small" net ", namely the "Internet of things". Based on this idea, called WInternet Iot design, and introduces the overall architecture, working mode and protocol system, and also discusses the several other issues worthy of further study. Keywords: Internet of things; Pipeline agreement; Cloud calculation; Technology application

1 Introduction

In recent years, the development of the Internet of things has been attached great importance to, academia, industry, the government to give great attention to the development of the Internet of things. Internet of things is considered can connect hundreds of millions of physical world objects, through monitoring, analysis and control of network information technology, the extension of human perception control ability has huge potential. Iot research work has been carried out. A lot of Iot

demonstration system was also developed, and has made remarkable application effect. But at the same time, the current development of the Internet of things is also facing some problems, especially all kinds of Internet of things generally are connected by "-" in the form of "network", although the implements of all kinds of physical objects in the local scope - machine is linked together, but different "net" resource sharing between the perception and control equipment. And because of the existing "- machine connected to the network is generally based on the special agreement, adapt to the need of the professional custom, cause a physical network is not open, hard to connectivity. To realize all kinds of network connectivity should be a Iot of development trend.

2 Internet development history and experience

2.1 Electronic equipment network systems

In the 19th century to early 20th century, electronic equipment network of prototype has emerged. As the time of the telephone network, cable network, and other various types is private network system. Now in retrospect, these networks have been gradually replaced by the Internet; its reason is worth thinking about. Analysis of the network system can be found early, they generally have the following features:

(1) Vertical integration, tightly coupled

The network system hardware, software and operation of the upper application mostly belong to an owner. Most of the various components of the integration in the network system is independently by the owner internal personnel, network in each part of the tightly coupled system.

(2) The proprietary protocols to exchange

In the network system of internal communication protocol is often according to the specific needs of each owner, in order to better the optimization and use of all kinds of equipment components are designed. Different owners of intellectual property rights and interests protection often will deal core part try to conceal, difficult to communication between different network systems. This method of "vertical integration, proprietary protocols" to satisfy the various network system of the optimization of resources and interests of the owner to protect specific needs, but

also directly led to the early electronic equipment network problems.

(3) Resource sharing difficult

Because every electronic device network system is generally adopts the way of "vertical integration" structure, the network system in all kinds of electronic equipment and software are also often can only be used for the network users of the system. For example in the early days of the telephone network system, multiple phone companies have independent laid their phone lines, set up relevant telephone switching equipment, a relatively independent telephone network. Different lines and equipment cannot be Shared between the telephone network, caused the repeat purchase, resource sharing difficult.

(4) Function to replicate

Another problem is that in the different network system to repeat the same or similar functions, such as the telephone network signaling in the instruction and the signal coding implementation. Features to replicate directly lead to two results: one is each owners are required for the design and implementation of general agreement and equipment, but due to the limitation of the technical strength of a single owner, will inevitably extend network independently design and development time; Second, under the limit of time and personnel, the realization of function module final quality more or less is not ideal. If different owners to cooperation, complementary advantages, functional modules will not only greatly shorten the development time, its quality will improve …… 此处隐藏：5886字，全部文档内容请下载后查看。喜欢就下载吧 ……
