Internet of things credible route selection method and system based on AGV and reputation system

Abstract

The invention discloses an internet of things credible route selection method based on an AGV and reputation system; the method comprises the following steps: S1: broadcasting and sending a relay node selection request message to a neighbor node by a source node; S2: receiving the request message and executing an LX-AGV (LinXu-Arrow-d' Aspremont-Gerard-Varet) mechanism by the neighbor node to feed back real information; S3: evaluating credibility of the source node and sending feedback information to indicate whether is willing to provide a relay service; and S4: after the source node receives the feedback information, carrying out credibility evaluation on the neighbor node which is willing to provide the relay service by adopting an AGV-based credit model, and selecting a relay node. Through above manner, the invention can dynamically reflect the behavior of the node and identifies an internal malicious node, effectively resists the intermittent attack inside, and improves the credibility and the robustness of a route selected with a route selection algorithm; and therefore, the establishment of a route path in an internet of things is safer and more credible, and the maintenance of the route is more timely and effective.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to an Internet of Things trusted routing selection method and system based on an AGV and a reputation mechanism. Background technique [0002] The Internet of Things means the internal connection of perception, the driving device of the network, following various forms of communication, such as human-to-human communication, human-to-object communication, single object to single object communication, one object to many objects Communication. The Internet of Things was first proposed by the Auto-ID Center in 1999. Since then, its research and development speed has begun to accelerate. Today, the Internet of Things realizes seamless large-scale sensing connection and Analysis of data. [0003] The Internet of Things must ensure the security of all layers. In the perception layer security, it includes routing protocol security, key management security, encryptio...

Problems solved by technology

[0006] The existing research results can guarantee the security performance of routing protocols in the Internet of Things and optimize the performance of routing protocols to a certain extent, but there are still the following deficiencies: (1) When ensuring that nodes provide real information, the budget balance of the system cannot be guaranteed (2) Lack of consideration of intermittent attacks on nodes in the network
