The core idea is to divide the network area where the nodes are into different types of hexagonal grids and nodes in different grids use different ways to create keys. Theoretical analysis and simulation results show that the scheme has better connectivity, local security and global security. In view of the existing storage consumption problems, a deterministic key establishment scheme is proposed based on the irregular network model. The simulation results show that the effective coding mechanism introduced optimizes the storage consumption in the network range. It also has a higher security threshold and absolute connectivity, and the enemy's ability to resist capture attacks is stronger.","PeriodicalId":387853,"journal":{"name":"Int. J.

The automatic patrolling of power lines was discussed in terms of algorithms. An unmanned aerial vehicle transmission line inspection method based on machine vision was proposed.

By Wiener filtering de-noising and probability density functions, the image clarity was improved. According to the existing tracking techniques and algorithms, a Camshaft target tracking algorithm based on lossless Kalman filter was proposed. The method of non-destructive Kalman filter was adopted to predict the region of interest of power line identification. Using the Camshaft algorithm, the prediction of the window was searched and the size of the window was adjusted. Transmission lines were tracked in real time. The results showed that the restoration effect of the algorithm was obvious. The clarity of the image was improved. It prepared for the extraction and tracking of the future transmission lines.
