Wireless sensor network topology construction method

Abstract

The invention relates to the network topology construction field, provides a wireless sensor network topology construction method. The wireless sensor network topology construction method comprises: step 100, constructing an initial scale-free wireless sensor network topology; step 200, optimizing the initial scale-free wireless sensor network topology according to the degree difference of every connection mode of the nodes on independent edges, thus obtaining a preliminarily optimized wireless sensor network topology; step 300, optimizing the preliminarily optimized wireless sensor network topology according to the summation of the circling angles of every connection mode of the nodes on independent edges, thus obtaining the wireless sensor network topology. According to the invention, the network topology has relatively high robustness in facing a random attack and a hostile attack without changing the node degree distribution of the nodes.

Description

technical field [0001] The invention relates to the field of network topology construction, in particular to a wireless sensor network topology construction method. Background technique [0002] Internet of Things technology (Internet of Things) is a huge complex that integrates multiple disciplines, including WSNs, embedded systems, topology query, intelligent control, data processing and task scheduling and other fields. WSNs usually deploy a large number of sensor nodes, aggregation nodes, and communication nodes in a distributed area. These nodes communicate with each other to form a multi-hop self-organizing network system to monitor and control physical variables in the environment, such as temperature, sound, light, etc. And can independently complete the assigned tasks according to the environmental requirements. In recent years, due to the increasingly harsh application environment of wireless sensor networks, the application scale has also expanded rapidly. Model...
