Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific examples.

[0022] A trust-based probabilistic label tracing method in a wireless sensor network. In the traceability process of a wireless sensor network, the probability of adding the unique identification information of the current routing node when the data packet passes through the routing node is related to the current routing node in the wireless sensor network. Trust is inversely proportional to settings.

[0023] When the trust degree of the routing node in the wireless sensor network changes, the rate of change of the probability of adding the unique identification information of the routing node to the data packets passing through the routing node is greater than the rate of change of the trust degree of the routing node.

[0024] The marking probability function with the above properties can make the marking probability high when the trust degree of the node is low, so as to q...

Abstract

The invention discloses a trust-based probabilistic label tracing method in a wireless sensor network. During the traceability and tracing process of a wireless sensor network, the probability of adding the unique identification information of the current routing node when a data packet passes through a routing node is the same as that of the current routing node in the wireless sensor network. Trust in sensor networks is set inversely. This method reduces the marking probability of data packets generated by most trusted nodes in the network, and improves the marking probability of data packets generated by a small number of suspicious nodes. On the whole, the total amount of marking information in the network is greatly reduced. On the basis of the ability to resist attacks, the life of the network is improved at the same time.

Description

technical field [0001] The invention belongs to the field of wireless sensor network security, in particular to a trust-based probabilistic label tracing method in a wireless sensor network. Background technique [0002] A wireless sensor network is a wireless network composed of a large number of sensor nodes that communicate with each other through multi-hop wireless links and in a self-organizing and multi-hop manner. It can be widely used in industrial monitoring, agriculture, civil, environmental monitoring, battlefield , ocean, fire and other special environments and applications, it is considered to be one of the key basic technologies of the future important IoT network. The security of wireless sensor networks is an important research topic. Among them, traceability is an important mechanism to ensure security in wireless sensor networks, and its research is of great significance. [0003] Traceability is an important mechanism to ensure the security of wireless s...
