Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings. A wireless sensor network improved LEACH method CGA-LEACH based on chaotic genetics in the present invention includes four parts: system model, population initialization, fitness function construction and chaotic genetic calculation. Construct a fitness function by considering energy consumption and load, use conditional chaotic mapping to generate real coded chromosomes, and use chaotic genetic selection, crossover and mutation operations to improve the convergence speed and find the optimal cluster head, thus forming a uniform distribution and energy consumption and load-balanced cluster structure. Ultimately, the network life cycle is effectively extended, the network load is balanced, and the energy efficiency of the network is improved.

Abstract

The present invention relates to an improved LEACH clustering routing method CGA-LEACH (an improved LEACH algorithm for wireless sensor network based on chaotic genetic algorithm) based on chaotic genetic wireless sensor network, the method includes system model, population initialization, fitness function construction And four parts of chaotic genetic operation. Construct a fitness function by considering energy consumption and load, use conditional chaotic mapping to generate real coded chromosomes, and use chaotic genetic selection, crossover and mutation operations to improve the convergence speed and find the optimal cluster head, thus forming a uniform distribution and energy consumption and load-balanced cluster structure. Ultimately, the network life cycle is effectively extended, the network load is balanced, and the energy efficiency of the network is improved.

Description

technical field [0001] The present invention relates to a wireless sensor network routing method, in particular to an improved LEACH routing method CGA-LEACH (an improved LEACH algorithm for wireless sensor network based on chaotic genetic algorithm) based on chaotic genetics. By constructing a new fitness function, and use chaotic genetic selection, crossover and mutation operations to form a cluster structure with uniform distribution, energy consumption and load balance, thereby prolonging the network life cycle. Background technique [0002] As one of the most important and basic information collection technologies in the real world, wireless sensor networks (WSNs) measure thermal, infrared, sonar, and seismic signals in the surrounding environment through nodes with built-in sensors. . Due to the limited resources of wireless sensor network nodes such as energy, how to save energy to prolong the network life cycle is the most important challenge for wireless sensor net...
