Improvement And Application Of LEACH Algorithm

Wireless sensor network is a comprehensive discipline for information acquisition and processing,It contains technologies such as sensors and wireless communication and is widely used in environmental monitoring,military and medical fields.Due to the limitations of hardware resources,power capacity,etc.,In order to monitor the indoor environment and effectively extend the life cycle of the network,it is necessary to improve the existing routing algorithms so as to design an effective energy-saving routing algorithm has also become one of the research priorities in the field of WSN,Its research value and market value is also growing.At first,the paper analyzes and compares the current development of wireless sensor networks and wireless sensor network routing algorithms at home and abroad and several typical wireless sensor network routing algorithms.LEACH algorithm as the starting point,Two main steps for the LEACH algorithm: the establishment of the cluster process and the stability of the process,respectively,to improve.Among them,the process of cluster establishment completes node clustering through the introduction of Venn diagrams;and stabilizes the process,and implements the inter-cluster routing in the form of multi-hop by introducing improved ant colony algorithm.By comparing the improved algorithm with the existing one,the simulation results show that the clustering process of the improved algorithm is more uniform than the LEACH algorithm and the distribution of the dead nodes is more uniform.In the process of communication between cluster head and Sink node,the improved algorithm can effectively balance the energy consumption among cluster heads and extend the life cycle of the whole network compared with LEACH and basic ant colony algorithm.In addition,the paper analyzes the current situation of greenhouse environmental monitoring system at home and abroad,Based on the requirements analysis,the improved multi-hop clustering routing algorithm is applied to cluster nodes and inter-cluster routes in the system.In the premise of ensuring that each sensor acquisition node can collect data in an energy-balanced manner and can perform data transmission in the WSN,the real-time monitoring of the environment in the greenhouse can be successfully realized through hardware design and software programming.In this paper,we provide the overall design scheme,hardware design and software implementation methods for the greenhouse environment monitoring system based on the Voronoi and the improved ant colony algorithm routing algorithm.
