Method and system for ensuring data transmission of wireless sensor network

Abstract

The invention is suitable for the technical field of communication, and provides a method and system for ensuring data transmission of a wireless sensor network. The method includes the steps of setting nodes, wherein a plurality of anchor nodes are arranged in an area where data need to be collected; authenticating the nodes, wherein security authentication is conducted on the ordinary nodes in the area through SINK ends of the wireless sensor network and the anchor nodes; transmitting the data, wherein each cluster head node transmits the data to the SINK ends in a preset multi-hop network mode after receiving the data transmitted by the ordinary nodes, passing the security authentication, in a cluster which the cluster head node belongs to. Thus, the problem of secret key hosting during WSN node security authentication is solved, and the secure data transmission of the WSN is achieved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for ensuring data transmission of a wireless sensor network. Background technique [0002] The emergence of wireless sensor networks (Wireless Sensor Networks, WSN) is a rapid development in the fields of micro-electro-mechanical systems (Micro-Electro-Mechanism System, MEMS), system on chip (System on Chip, SoC), wireless communication and low-power embedded technology. result of development. It has brought about a revolution in information perception with the characteristics of low power consumption, low cost, distribution and self-organization. Wireless sensor network is a multi-hop self-organizing network formed by a large number of cheap micro sensor nodes deployed in the monitoring area through wireless communication. [0003] In recent years, the rapid development of sensor technology has been widely used in all walks of life, especially in som...

Problems solved by technology

However, the security issue has always been a problem that has plagued the development of the WSN field. In the past, under the limited hardware conditions, it was a very difficult task to ensure security. The general chip storage space is relatively small, and this limited space needs to be completed. There is a lot of work, first of all, there needs to be a hexadecimal program that runs all the time, and secondly, there needs to be a part that is used to temporarily store the data collected in real time

[0006] In summary, the existing wireless sensor network data security transmission technology, in actual use, obviously has inconvenience and defects, so it is necessary to improve
