Problems solved by technology

However, in the design of the traditional industrial wireless sensor network deployment method, the sensor nodes or cluster head nodes are deployed at the intersection of the grid, so that the actual deployment does not allow the deviation of the node position, which increases the difficulty of the actual installation of the industrial wireless sensor network nodes and is practical. The robustness in the application is poor, so it does not meet the actual industrial wireless sensor network application requirements

Abstract

The invention discloses a method for optimizing Pareto multiple target deployment of an industrial wireless sensor network, and relates to the field of industrial automation and intelligent computing. A new communication model is defined for the two-layer cluster structure industrial wireless sensor network commonly used in the industry, the method for optimizing the Pareto multiple target deployment is provided, the cluster head node deploying position is optimized through the Pareto human study optimization algorithm, and the multi-objective optimization of reliability, real-time performance, economical efficiency and expansibility of the industrial wireless sensor network is achieved by providing redundant cluster heads, optimizing and limiting the hop count to a base station from a sensor node, reducing the number of the cluster heads, balancing the cluster head charge number, and reserving network access ports needed by mobile nodes and upgrading and maintaining of a system.

Description

technical field [0001] The invention relates to two major fields of industrial automation and intelligent computing, in particular to an industrial wireless sensor network Pareto multi-objective deployment optimization method. [0002] Background technique [0003] Today, in order to improve process control efficiency, comply with environmental regulations, and meet the needs of economic goals, industrial automation systems are commonly used in large-scale industrial systems. Over the past few decades, wired industrial communications, such as fieldbus systems and wired HART, have been widely used in factory automation and process automation, increasing the productivity and efficiency of industrial systems. However, installing and routing cables in harsh industrial environments remains difficult and expensive. Especially for industrial remote monitoring, the cost of installing industrial cables is even higher than the cost of the sensor itself. At the same ti...
