Embodiment 1

[0156] Based on the simulation parameters in Table 1, this embodiment simulates a named data-based Internet of Things data communication method in the present invention. After the network is started, each node executes steps 101-107 to establish an index table; if the node creates a data, then perform steps 401-408 to publish data; if a node detects that the neighbor node can provide the required data through the index table, then obtain the data by performing steps 201-210; if the node cannot obtain data through the neighbor node, then pass Execute steps 301-315 to obtain data, and if the node still cannot obtain data through steps 301-315, execute steps 501-516 to obtain data. The performance analysis of this communication method is as follows: when the node moving speed increases, the network performance decreases, and the data communication delay increases; when the node moving speed decreases, the network performance increases, the data communication delay decreases, and t...

Abstract

The invention provides an Internet of Things (IoT) data communication method based on named data. The IoT comprises more than one node, wherein each node is configured with a wireless interface, a piece of data has a unique data identifier (ID), and the data ID is a positive integer more than 0; a message comprises a message type, the data ID, a broadcasting range and a load domain. By using the method provided by the invention, the user can quickly acquire the data, and thus the data communication delay and cost are reduced, and the quality of service is improved. The method provided by the invention can be applied to the fields of smart home environment monitoring and road condition monitoring, and has the wide application prospect.

Description

technical field [0001] The present invention relates to a communication method, in particular to a data communication method of the Internet of Things based on named data. Background technique [0002] IoT is a new service model. In recent years, a lot of research work has been devoted to the Internet of Things so that users can quickly obtain network services. With the development of network technology, the Internet of Things will become a mode of providing services in the future. At present, the data communication delay and cost of the Internet of Things are relatively large, which reduces the performance of network services. Therefore, how to reduce the delay and cost of IoT services has become a hot research topic in recent years. Contents of the invention [0003] Purpose of the invention: The technical problem to be solved by the present invention is to provide a data communication method for the Internet of Things based on named data for the deficiencies of the p...
