Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] A low-power safe routing control method based on gray correlation and distance analysis in the present invention consists of four parts, namely system model, clustering based on gray correlation analysis method, intra-cluster security perception and routing selection. The system model provides a model for protocol implementation, including network model, energy model and network topology; clustering based on the gray correlation analysis method utilizes the characteristic that the data sensed by spatially adjacent sensor nodes has a certain correlation, and the correlation degree is relatively high. High nodes are divided into a cluster area; intra-cluster trust evaluation is to compare and analyze the data packets received by the cluster head with the data packets perceived by itself, and combine the distance vector method and polynomial fitting method to scre...

Abstract

The invention discloses a low-power-consumption secure routing control method based on grey correlation and distance analysis, and aims to solve the technical problems that a trust evaluation mechanism in an existing wireless sensor network routing protocol needs to acquire data in multiple aspects, and the communication energy consumption is relatively high. The method comprises the following steps of: dynamically clustering in a network by adopting a grey correlation analysis method according to the characteristic that sensing data of sensor nodes has space-time correlation; and the cluster head node analyzes the data sent by the nodes in the cluster by adopting a mode of combining a distance vector method and polynomial fitting, and judges the security of the nodes. According to the protocol, a large amount of data transmission between an evaluation node and an evaluated node in a trust evaluation mechanism is avoided, the network energy consumption is reduced while the network security is ensured, the network survival time is prolonged, and the protocol can also be well applied to a scene in which the security state of the sensor network is unknown.

Description

technical field [0001] The invention designs a low-power safe routing control method based on gray correlation and distance analysis, which belongs to the research field of wireless sensor network routing protocols. The protocol uses the gray relational analysis method to divide the network into several independent cluster areas. In each cluster area, the cluster head node screens malicious nodes based on the received data of the nodes in the cluster, combined with the distance vector method and polynomial fitting. Finally, according to the energy density, location and other information of the neighboring cluster head nodes, the routing node with the optimal evaluation value is selected to determine the routing path. Background technique [0002] Security is one of the performances that need to be focused on in the design of wireless sensor network routing protocols. Many scholars in the field of wireless sensor networks have carried out research on this. Routing protocols ...
