A trust evaluation method for sensor cloud underlying nodes based on mobile fog nodes

Abstract

The present invention relates to a method for trust evaluation of sensor cloud bottom layer nodes based on mobile fog nodes. The sensor node of the fog node is called a relay node; the fog node visits the relay nodes in the queue to be visited in turn, and every time it moves to a relay node, it calculates all the sensor nodes adjacent to the relay node The comprehensive trust evaluation; the comprehensive trust evaluation includes energy trust evaluation, data trust evaluation and comprehensive communication trust evaluation. The invention introduces mobile fog nodes into the sensor cloud system to perform trust evaluation on the underlying sensor network, which can reduce the energy consumption of trust evaluation in the sensor cloud system, improve the efficiency of trust evaluation, and effectively detect malicious nodes in the network.

Description

technical field

[0001] The invention belongs to the field of information security in large-scale sensor clouds, and in particular relates to a sensor cloud bottom layer node trust evaluation method based on mobile fog nodes. Background technique

[0002] Wireless sensor networks are widely used in many fields such as industrial control, smart home and consumer electronics, smart precision agriculture, environmental perception and health detection. However, due to the limitations of computing power and storage capacity, a large amount of sensor data cannot be effectively processed and analyzed. In recent years, with the development of cloud computing technology, researchers have gradually turned their attention to the combination of cloud computing technology and wireless sensor networks. Cloud computing technology expands the application space of sensor networks, and also provides new ideas for solving many limitations of sensor networks, such as providing strong support fo...
