Embodiment Construction

[0024] Before any embodiment of the invention is described in detail, it is to be understood that the invention is not limited in application to the details of construction shown in the following description or in the accompanying drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative improvements belong to the protection scope of the present invention.

[0025] The system time in the power Internet of Things network is fixed, and the communication between each node on the network is possible. The route discovery method is executed in parallel on each node of the network, and each node performs the same steps, so that the method can be implemented within a limited number of steps. achieve convergence.

Abstract

The invention discloses a bidirectional feedback routing discovery method and device suitable for an electric power Internet of Things environment, relates to the technical field of electric power Internet of Things, and solves the problem that all nodes cannot discover routing information of other nodes in time in an electric power Internet of Things network of which the height of each node changes dynamically and there is no central server. According to the method, in each round, each node v in the power Internet of Things sends an own routing resource update set T(v)update to each node u inan initial list according to the own initial list; after receiving the information, the node u feeds back currently known new routing information to the node v, and then updates the T(u) of the nodeu; the node v updates the understanding set T (v) of the node v according to the feedback information; and the above steps are repeated until the whole algorithm converges. According to the invention,each node in the network can timely and effectively discover the routing information of other nodes in the network.

Description

technical field [0001] The invention relates to the technical field of electric power internet of things, in particular to a bidirectional feedback routing discovery method and device suitable for the environment of electric power Internet of things. Background technique [0002] As more and more power equipment and related applications continue to join the power Internet of Things, the dynamics and uncertainty of the network have increased significantly. Routing is a closely watched issue in communication networks, and different methods have a great impact on the overall performance of the network. In the power Internet of Things environment, through network connection and information exchange, each other discovers the routing resources owned by each other's nodes. This problem is called the routing discovery problem. The node communication method used to enable all nodes in the entire network to know the routing information of all other nodes is called the route discovery...
