Design of Agricultural Wireless Sensor Node Deployment Algorithm Based on Genetic Algorithm

Agricultural wireless sensor network is an important application of Internet of Things technology in agricultural field.Deployment of agricultural wireless sensor nodes is an important factor limiting its life cycle.In order to improve utilization of detection range of agricultural wireless sensor network nodes，reduce transmission data redundancy and prolong life cycle of wireless sensor networks，based on random deployment，an iterative wireless sensor node deployment algorithm was proposed.The algorithm used genetic algorithm to optimize solution，took coverage as adaptation function and used discrete graphic calculation to realize function.The algorithm could obtain deployment scheme with high coverage under condition of a certain number of sensors.
