Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0043] Such as figure 1 , figure 2 As shown, the establishment process of the trust mechanism of the present invention is illustrated with a schematic diagram and a block diagram of the trust mechanism of the wireless sensor network layered routing protocol of the present invention. There are n cluster nodes in a cluster, and the cluster head node collects these cluster members. Calculate the current trust value of the nodes in the cluster after the interaction information of the nodes in the cluster; the sub-cluster head calculates the current trust value of the cluster head node of the cluster according to the success rate of forwarding data packets from the cluster head node to the sink nod...

Abstract

The invention relates to a method for establishing a trust mechanism of a network hierarchical routing protocol of a wireless sensor, comprising the following steps of: collecting successfully interacted histories of a node in a cluster in a round of time slots by a cluster head node; recording the successfully interacted histories of the cluster head node in a round of time slots by a secondary cluster head node; forming the current trust values of all nodes; after gathering the current trust values of all the nodes by a sink node, combining a historical trust record, synthesizing a final trust value TV of each node; dynamically evaluating all nodes by the sink node according to the level of the final trust value of the whole network to divide the nodes into a creditable level, a generallevel and a trustless level; finally, dividing and selecting the creditable nodes as candidate cluster heads according to the levels; and excluding the trustless nodes out of the network. The invention enables the nodes to reliably complete work tasks, is not influenced by node failure and hostile attack and prolongs a life cycle of a clustering network.

Description

technical field [0001] The invention belongs to the field of communication security of wireless sensor networks, in particular, the invention relates to a method for establishing a trust mechanism of a wireless sensor network layered routing protocol, which converts the respective interaction records of nodes in a cluster and cluster head nodes into their own trust values security metrics and apply them to the routing of infinite sensor networks. Background technique [0002] Wireless sensor networks (Wireless Sensor Networks) are highly concerned by academic and industrial circles all over the world because of its highly interdisciplinary nature and broad application prospects. The wireless sensor network is composed of a large number of sensor nodes through multi-hop wireless communication, and it does not depend on the basic network facilities. Each node acts as a host and a router in the network at the same time. The purpose is to cooperate in perception, collect and pr...
