specific Embodiment approach

[0030] According to the Hyde balance theory that guides the public's cognition, the present invention improves the reputation framework RFSN for the actual unreliable channels, and improves the observation mode of node behavior and the calculation method of direct reputation.

[0031] Hyde's theory starts from the coordination of interpersonal relationships, and believes that in a simple cognitive system, if the individual and the public have inconsistent attitudes towards things, there will be an imbalanced state, and in this state, the individual will be under great emotional pressure. , and will want to return to equilibrium. A state of equilibrium refers to a state in which what is observed does not contradict the past position of the observer.

[0032] Due to the unreliability of the actual channel, problems such as packet loss, noise interference, external attacks, and hidden nodes will lead to uncertainty in the detection of behavioral events by nodes, which will affect...

Abstract

The invention relates to a trust value calculation method for wireless sensor network based on unreliable channel and trusted management scheme, especially for unreliable channel condition as high packet loss and severe hidden nodes. The method proposes a trust structure HRFSN based on Heider's balance theory and public nodes of interacted two parties directly participates in observation activity for observing the nodes to optimize direct trust value calculation under unreliable channel so as to increase reliability of trust value. The method changes direct trust value observation style and calculation method of trust management scheme of known wireless sensor network, can acquire more accurate direct trust value and further more reliable trust value. The method, with relatively high scientificity and higher application value, can provide more accurate trust foundation during cooperation of sensor node.

Description

technical field [0001] The invention belongs to the field of wireless sensor network trust management, and specifically relates to a wireless sensor network reputation value calculation method based on an unreliable channel for improving direct reputation values ​​based on Hyde theory and using direct observation values ​​of public neighbors. Background technique [0002] Because of its low cost and easy deployment, wireless sensor networks are widely used in battlefield target tracking, building safety monitoring, forest fire detection, etc., and become the best candidate for the information extraction front-end of the next generation of high-performance information systems. However, sensor nodes are often deployed in an uncontrolled complex environment, and they have the characteristics of fragile capabilities and limited resources, so that attackers can capture nodes without being noticed, modify them, and send Misleading the operation of sensor networks by erroneous data...
