Why is the development of the Internet of things so slow

In our side now as you can see many iot devices, big to wisdom city, no shops, small to the intelligent hand ring, intelligent temperature control instrument, etc., we have already enjoy the convenience brought about by the Internet of things, but at the same time, all interconnected in the science fiction film scene is still more distant, we always habitually close enough to the forecast of future, but technology found obviously pull far our distance with the future. In short, the Internet of things is still very slow.

, of course, if we say, is relatively slow, the concept of Internet of things is in 1999, was formally put forward, after nearly 20 years of development, now if only from the Internet itself, its technology has been considerable progress, a breakthrough from scratch. However, the development of the Internet of things has not satisfied people's increasing consumption concept, and many other reasons have caused the current Internet of things to remain at a low speed.

The slow development of the Internet of things.

Why if you want to search for the Internet of things development is slow, at present can induce the following several reasons, one is unable to keep up with the basic research, as is known to all, the Internet of things depends on many sensors connected through the network, data interaction, and finally formed the whole system of Internet of things, so accurate, Internet of things is essentially a kind of sensor network, self-organization and multiple hops network (wireless sensor network, AD - hoc network, wireless multi - hop network).

But implementing a distributed sensor network is not as easy as it might be. Traditional wireless networks such as honeycomb, WLAN, etc., can achieve better communication by optimizing routing and bandwidth allocation strategy in the case of high-speed mobile.

But this approach is flawed on the sensor network, first of all, is limited by the supply of energy, at present can only take batteries or solar power, not directly provide energy, so the focus of the current sensor design case is to ensure that the whole function maximize energy efficiency and increase the life cycle of the network.

Secondly, the transmitting distance of the wireless module is positively correlated with the transmitting power, but how should the communication node be solved when the distance between the communication nodes is greater than the maximum emission distance? Finally, when the wireless node has no power, how to solve it?

These three problems are the three basic problems in the research of wireless sensor network, and almost all of them are overcoming these three difficulties. If these three problems are not solved, then wireless sensor networks will be impossible to talk about, let alone the commercialization of the Internet of things.

How to solve the key problem of slow Internet development?

At present, there are some corresponding solutions to these three basic problems. There have been many researches on the first route strategy, such as flood (Flooding), SPIN, directional diffusion and so on. Then how to solve the communication distance problem, resulting in the multi-hop network and network.

Multiple hops network is easy to understand, in order to reduce the node energy loss brought by the wireless transmitting distance, nodes can send data to another recent node, the data by means of the baton to detract from the least to pass down, this is multiple hops network (multi - hop); And organize network (AD hoc) is complicated, the organization of each nodes in the network even if the network nodes and routers, and each node can be as a gateway and the network communication, at the same time can also be forwarding packets, this makes on the transfer of data can have a variety of ways, and how to choose the optimal method for data transfer is the next challenge.

As for the last question, how to supply energy to the nodes, because the efficiency of solar energy conversion is still not high, so the power supply from solar energy will not be captured.

The easiest and simplest way to do this is to replace the battery, but it wastes a lot of time. So now is working through the modulation of space electromagnetic signal reflection scattering link power and communications, wireless charging technology, so that you can thoroughly solve the problem of power supply, but from the experiment to the commercial is still some way to go.

These are the bottlenecks in the development of the Internet of things from the perspective of sensor technology. Besides technical factors, there are many other reasons for the development of the Internet of things.

Weak demand standards are in disarray.

Bear the brunt of nature is the weak of demand, at present the application of Internet of things end, except in commercial or industrial use in the application of personal consumption, has not yet appeared, this process has led to the development of the Internet of things is not explosive propulsion.

Second, because of the Internet of things now is still in a state of chaos, but just a IoT wireless connection technology standard is the NB - IoT, LoRa, ECGSM, eMTC, etc., can't uniform standard, make IoT hardware cost is high.

In addition to the hardware, software ecology is hard to build, and now the Internet of things companies even have to package the software and hardware through a package.

But with the development of technology, also with animal production of network data, and how do these data security protection, and the resulting legal questions about user privacy data, which limits the development of the Internet of things.

Of course with 5 g and the development of artificial intelligence, Internet of things will also striding across under the drive of these technologies, which will help to solve the problem on the Internet of things technology and standard, and the solution of these problems will bring animals networking the establishment of ecological and Internet of things will also gradually improve the construction.

The development of the Internet of things should also be driven by technology.

For now, the most important issue is still in demand of Internet of things, and demand is the power of a technological progress, how to activate the market demand for the Internet of things, is also the most need to solve the key, so you can see many propaganda for the Internet of things, it is in order to guide the market acceptance of iot, lay a foundation for the future development of Internet of things.

The future of the Internet of things is infinite possibility, but for now, the development of the Internet of tuyere has not now, but not to feel anxious, but we expect too much for the Internet of things and, as a result of the Internet itself has been steadily advancing.

In Bill Gates's "the road to the future", we always overestimate the changes that will take place over the next two years and underestimate the changes that will take place over the next decade. The future of the Internet of things is undoubtedly bright, and we just have to wait for it to arrive.
