Conflict judgment-based trust management method in underwater acoustic sensor network

Abstract

The invention discloses a conflict judgment-based trust management method in an underwater acoustic sensor network, which is used for solving the problem of mutual conflict of recommendation information of a plurality of third-party nodes in a trust management mechanism. According to the method, firstly, a trust decision-making method based on node reliability and link reliability is provided by combining the characteristics of node interaction and the characteristics of an underwater acoustic sensor network; in addition, the invention provides an incentive mechanism based on capturer dilemma, which balances the energy consumption of the trust recommendation process and the accuracy of the trust recommendation result.

Description

Technical field: [0001] The invention belongs to the technical field of radio networks, and in particular relates to a trust conflict resolution method in a trust management mechanism in an underwater acoustic sensor network. Background technique: [0002] As an important part of the development of marine economy, Underwater Acoustic Sensor Networks (UASNs) have great application value in environmental monitoring, auxiliary navigation, military operations and many other aspects. UASNs realize real-time monitoring of the marine environment by sensing data, collecting data, and transmitting data. Since underwater nodes are deployed in an open and unmanned environment, they are vulnerable to attack and destruction. Therefore, designing an effective security mechanism for UASNs is crucial for data transmission. [0003] Traditional encryption algorithms are not suitable for resource-constrained UASNs, and authentication schemes cannot resist insider attacks. Therefore, the tr...

Problems solved by technology

However, most trust management mechanisms focus on the calculation and update of trust values, and they seldom or do not consider the vulnerability of the trust mechanism itself

Especially with the development of complex and dynamic wireless networks, the trust calculation process inevitably requires recommendation information from third-party nodes. When the recommendation information conflicts with each other, the trust decision-making process will become complicated.

There have been a lot of studies on trust recommendation conflicts, but most of the traditional studies only consider the conflict of recommendation information caused by dishonest recommendations, without distinguishing between dishonest recommendations and wrong recommendations.

The dishonest recommendation attack is the subjective malicious attack behavior of the third-party node, but the wrong recommendation is the objective judgment error of the third-party node

In this paper, based on node interaction heterogeneity and underwater acoustic channel instability, a trust decision-making method is proposed to solve the wrong recommendation problem in UASNs
