Problems solved by technology
It can be seen from this that the biggest feature that distinguishes it from traditional IP is that it pays more attention to the content itself rather than the storage location of the content, which fundamentally changes the encapsulation structure and addressing mode of IP packets, which is conducive to cross-region mobile communication devices Switching reduces communication delay and solves problems such as inability to cope with high-speed mobile communication, exhaustion of IP address space, low network transmission efficiency, and poor security under the traditional Internet architecture

Embodiment
[0018] The data collection sender and the data request receiver are located in the same Wifi environment.
[0019] The data collection sender collects data in real time through USB, stores the collected data into a file, and judges whether the file is empty. If it is empty, it will re-collect the data; if it is not empty, it will extract the data in the file in groups. The naming and packaging of the data packets are performed through the named data network, and an entry is added in the data cache (Content Store) inside the routing node. When the cached entry has not expired, if there is a request packet requesting this name packet, the data cache will be queried. Once there is an entry with the same name or the longest common prefix name, the cached content packet will pass through the routing forwarding plane along the The reverse path of the request packet transmission is returned. After the return is successful, the data collection sender automatically changes the name of ...

The invention discloses a communication method for content-oriented internet of things networking data acquisition and distribution, which comprises real-time data sending, data acquisition sending and data request receiving, and is characterized in that a real-time data sending end and a data acquisition sending end are connected through a USB to realize real-time data acquisition; data acquisition, data packaging and data forwarding are sequentially completed by data acquisition and sending; data storage, data packet analysis and data forwarding are sequentially completed through data request receiving, communication of data collection sending and data request receiving is inverse, and when multiple data request receiving ends request for real-time data, the requirements of multiple request ends can be met at the same time. According to the invention, the requirements of the content-oriented Internet of Things for networking communication reliability, mobility and the like of data acquisition and distribution can be met. Taking Internet of Things networking adopting a named data network architecture as an example, wireless transmission of real-time data between a data acquisitionsending end and a data request receiving end can be realized.
Description
technical field [0001] The invention belongs to the field of content-oriented Internet of Things networking communication, and is particularly aimed at the requirements of its routing nodes in terms of data collection and distribution reliability, mobility and the like. Background technique [0002] Information-Centric Networking (ICN) is a brand-new Internet communication architecture. It is a network of data content interconnection rather than host interconnection. Its core object is information, and each information is identified by the name of the data. unit. Each node and program in the entire network is driven by various information request and response behaviors, and the ICN network function is to coordinate the transmission and cache of related named data, and use intelligent optimization to query the correct data to quickly respond to user needs. It can be seen from this that the biggest feature different from traditional IP is that it pays more attention to the co...
