Everything is a hot topic in the IT field that is worthy of attention today and even in the future. Users of different types of terminal devices generate data and information during use and application. These data and information need to be applied to cloud computing technology in the process of utilization. To serve the users, more and more data has formed what we call "massive data", so that big data is formed.
You and I will become the nodes of the Internet of Things.
The Internet of Things field has been very hot in recent years, and some researchers in the industry have said that each of our users will become a small node in the entire Internet of Things field in the future. European researchers believe that we have the sensing and The data transmission device can be used to form a cooperative ad hoc network. These networks will be used for group indoor navigation, crowd movement capture, large-scale health monitoring, and, most importantly, collaborative communication. Last week, the French agency CEA-LeTI and three universities launched a Cormoran project to explore the application of such a human-made network.
The concept of wireless body area networks (WBANs) is not new, and Apple and Heapslylon (smart socks) are exploring the possibility of using embedded sensors in clothing to establish connections. We are already in the era of wearable devices, from Google Glass to Pebble, they are an extension of our senses and actions.
All of these devices will become endpoints of the Internet of Things, but Cormoran is not making them the end of data, but forming a distributed ad hoc network to achieve mutual data transmission, and this network as we are in physics The movement of the world keeps changing.
What is the use of distributed computing technology?
First of all, the current point-to-multipoint transmission method in the field of mobile data communication is inefficient. The wearable device is usually connected to the mobile phone through Bluetooth first, and then the latter transmits the data to the nearest signal service base station. Even if the device finally establishes a network connection, the management cost of the transmission method and data is very expensive. And distributed computing mode can aggregate data around hundreds or even thousands of devices, and then choose the most efficient path to migrate data to the Internet. This way of collaboration is the same as the wireless system optimization proposed by Open Technology InsTItute.
If everyone is sharing their network connections and is willing to pass on data to others, everyone on the network will benefit, which is a bit similar to the meaning of cloud computing services, and secondly, collaborative LAN and automotive Vehicle connection technology has a lot in common. If the vehicles on the road can communicate with each other, they can coordinate with each other, avoid accidents and reach the destination quickly, but these networks may be attacked. The driver's personal information may be leaked or someone can falsify the data and cause a traffic accident.
