Problems solved by technology

However, due to the complexity of the urban indoor environment or the uncertainty of the outdoor environment, the GPS signal is in a weak or no signal state, which puts forward higher requirements for safe and reliable positioning
[0003] Usually nodes obtain their location information from GPS, however without GPS signal, it is difficult to know the location of all nodes, and it is difficult for a node to verify the authenticity of the location broadcasted by other nodes

Abstract

The invention discloses a mobile terminal self-organizing network positioning method based on a blockchain. A mobile terminal network comprises multiple nodes, node information of the nodes is stored in the form of blocks, multiple blocks form a blockchain, block data in the blockchain is the node information of the nodes, and the node information at least includes the relative location information of adjacent nodes. The method comprises the following steps: searching the relative location information of the adjacent nodes in the blockchain; and acquiring a relative location among the nodes and the relative location in the blockchain according to the relative location information of the adjacent nodes in the blockchain. According to the mobile terminal self-organizing network positioning method disclosed by the invention, the blocks in the blockchain can be regarded as trusted nodes of a consensus mechanism, and users in the mobile terminal network can accurately position the own location information in a communication network without relying on a trusted third party in case of no GPS signals or weak GPS signals according to the characteristics of the blockchain.

Description

technical field [0001] The invention relates to the technical field of cryptography of an information security center, in particular to a block chain-based mobile terminal network positioning method. Background technique [0002] The smart mobile Internet has gradually penetrated into all aspects of people's lives. Judging from the development trend of mobile Internet smart devices in recent years, the number of smart mobile terminals represented by smart phones has been in a state of rapid growth. With the popularization of smart devices, the positioning function of smart devices has been widely used. Ensuring the security and reliability of location information is an important prerequisite for ensuring a good user experience. However, due to the complexity of the urban indoor environment or the uncertainty of the outdoor environment, the GPS signal is in a weak or no signal state, which puts forward higher requirements for safe and reliable positioning. [0003] Usually n...
