AI, 5G: The development of the Internet of Things has become slow?


Introduction: Nowadays, we can already see many Internet of Things devices around us, from smart cities, unmanned shops, smart bracelets, intelligent temperature controllers, etc. We have already enjoyed the convenience of the Internet of Things. But at the same time, the scene of the Internet of Everything in science fiction movies is still far away. Simply put, the development of the Internet of Things is still very slow.

Nowadays, we can already see many Internet of Things devices, such as smart cities, unmanned shops, smart bracelets, intelligent temperature controllers, etc. We have already enjoyed the convenience brought about by the Internet of Things, but with At the same time, the scenes of interconnectedness in science fiction movies are still far away. We always habitually predict the future to be close enough, and the discovery of technology has clearly distanced us from the future. In short, the development of the Internet of Things is still very slow today.

Of course, if you say that slowness is only relative, the concept of the Internet of Things was formally proposed in 1999. Today, after nearly 20 years of development, if you only start from the Internet of Things, its technological progress is already quite large. Breakthrough. However, today's development of the Internet of Things has not been able to meet the increasing consumer attitudes of the people. Coupled with many other reasons, the current Internet of Things continues to be in a state of slow development.

Slowly developing Internet of Things

If we want to explore why the development of the Internet of Things is still slow, we can now sum up the following reasons. One of them is that basic research cannot keep up. As we all know, the Internet of Things relies on a large number of sensors connected through the Internet to interact with data, and finally form the entire Internet of Things system. Therefore, the IoT is essentially a sensor network, self-organizing, and multi-hop network.

But trying to implement a distributed sensor acquisition network is not as easy as imagined. Traditional wireless networks, such as cellular and WLAN, can achieve better communication intelligence by optimizing routing and bandwidth allocation strategies in high-speed mobility. However, this solution is flawed in the sensor network. First of all, it is limited by the supply of energy. At present, only battery or solar energy can be used to provide power, so it is impossible to provide energy directly. Therefore, the focus of the current sensor design is to ensure maximum functionality. Energy conservation and increase the network's life cycle.

Second, the transmission distance of the wireless module is positively correlated with the transmission power, but how can the problem be solved when the distance between communication nodes is greater than the maximum transmission distance? Finally, how do you solve the problem when the wireless node is dead?

It can be said that the above-mentioned three problems are the three most fundamental problems in the current research of wireless sensor networks. Almost all the researches are to overcome these three difficulties. If these three problems are not solved, wireless sensor networks cannot be discussed, let alone the commercialization of the Internet of Things.

How to solve

What are the key issues that slow down the development of the Internet of Things?

Currently there are some corresponding solutions for these three basic problems on the market. The first routing strategy problem has been studied by many academic circles. Plane routing strategies such as flooding, SPIN, directed diffusion, and so on. Then how to solve the communication distance problem, resulting in a multi-hop network and organizational network.

The multi-hop network is well understood. To reduce the energy loss caused by the node's wireless transmission distance, the node will send the data to the nearest other node. The data will be transmitted in the way of minimizing the loss through the baton. This is how much Multi-hop networks, while ad-hoc networks are more complex. Every node in an organization network is both a network node and a router. Each node can act as a gateway and an external network. Data packets can also be forwarded, which allows multiple ways to transfer data, and how to choose the optimal way for data transfer is the next challenge.

As for the last question, how to power the nodes, because the efficiency of solar energy conversion is still not high at present, so the use of solar energy to supply power will be incompetent. The easiest and most straightforward way to do this is to replace the battery, but this will waste a lot of time. Therefore, we are now studying the use of electromagnetic signals in the modulation and scattering link to provide energy and communication, that is, wireless charging technology, which can completely solve the power supply problem, but still have some way to go from experiment to commercial use.

The above is the bottleneck of the development of the Internet of Things from the perspective of sensor technology. In addition to technical factors, there are many other aspects of the development of the Internet of Things.

Weak demand

First of all, nature is weak in demand. At present, apart from being used in commercial or industrial applications, the application of the Internet of Things has not shown its application in personal consumption. This has also led to the development of the Internet of Things that has failed to advance explosively.

Second, because the Internet of Things is still in a state of confusion, there are NB-IoT, LoRa, ECGSM, eMTC, etc. standards for a wireless networking technology for the Internet of Things. The unified standard cannot be achieved, making the cost of the IoT hardware high. .

In addition to hardware, the software ecosystem is even more difficult to build. Today's Internet of Things companies even have to package software and hardware to provide one-stop service.

With the development of technology, it also brings with it the production of animal networking data. How to ensure the security of these data, and the legal issues concerning the collection of user privacy data, have limited the development of the Internet of Things.

Of course, with the development of 5G and artificial intelligence, the Internet of Things will also be striding across these technologies. This will help solve the problems of the Internet of Things technology and standards, and the resolution of these issues will also lead to animal networking. The establishment of an ecological environment will gradually improve the construction of the Internet of Things.

The development of the Internet of Things must also be driven by technology

At present, the most important issue is still in the demand side of the Internet of Things, and demand is a driving force for technological progress. How to activate the market's demand for the Internet of Things is also the key to the most urgent need to solve. Therefore, many things can be seen. The promotion of networking is to guide the market to embrace the Internet of Things and lay the foundation for the future development of the Internet of Things.

The future of the Internet of Things is bound to have unlimited possibilities. However, for the moment, the enthusiasm for the development of the Internet of Things is still lingering, but we do not feel anxious about this, but only because our expectations for the Internet of Things are too high. The networking itself has also steadily progressed.

In Bill Gates's "The Road to the Future", we have always overestimated the changes that will occur in the next two years and overestimated the changes that will occur in the next decade. The future of the Internet of Things is undoubtedly bright, and we just wait for it to arrive.
