Problems solved by technology

However, the communication environment in three-dimensional space is more complex and has stricter energy constraints, especially in the wireless sensor network formed by self-organization or orchestration with quadrotor UAVs as network nodes in high altitude.
In 3D application scenarios, existing network clustering methods are not ideal

Abstract

The invention relates to a real time positioning topology control method for a three-dimensional wireless sensor network, and belongs to the technical field of the wireless sensor network. According to the method, a simulation environment is initialized, all nodes are located in discovery states, each node is equipped with a unique mark, and all nodes obtain current positioning coordinate information according to a positioning algorithm; a whole three-dimensional space is divided into multiple cells according to hexagonal prism segmentation construction according to the current positioning coordinate information of all nodes and the communication radiuses of all nodes, and each node records the mark of the cell in which each node is located; general nodes in each cell generate own node exchange information; the general nodes in each cell enter a cluster head election stage, and the cluster head node in each cell is elected; and the general nodes in each cell enter a cluster head alternating stage. According to the method, the energy consumption is effectively reduced through application of space clustering, intra-cluster sleep and state conversion mechanisms.

Description

technical field [0001] The invention relates to a real-time positioning topology control method for a three-dimensional wireless sensor network, belonging to the technical field of wireless sensor networks. Background technique [0002] Sensor nodes in wireless sensor networks are assumed to be distributed on a two-dimensional plane. This is a very good approximation for networks deployed on the ground or where the height of the network is smaller than the transmission radius of the nodes. In these networks, the height of the network is negligible compared to its length and width. However, this two-dimensional plane assumption is not applicable to scenarios where the network height is large such as underwater, air, underground, and buildings, and nodes are distributed in three-dimensional space. Although the current application of these networks is relatively small, the use of 3D wireless sensor networks in many fields is becoming more and more common. For example, underw...
