Design of Optimal Coverage Deployment Algorithm for Large Difference Wireless Sensor Network Nodes
Wireless sensor networks have the problems of poor node deployment effect and low coverage probability in the case of large differences in node energy consumption.Therefore,a new optimal node coverage deployment algorithm for wireless sensor networks with large differences is designed.The minimum number of deployed nodes is determined from the angle of large difference in node energy consumption through the triangular lattice arrangement method,and the nodes are initially deployed.The ion bond oriented particle swarm optimization coverage algorithm is introduced,and the ion bond guidance is added to the particle swarm optimization algorithm to obtain the optimal location of nodes,so as to obtain the optimal deployment of network nodes,therefore,the design of the optimal cover-age deployment algorithm of network nodes is realized.The simulation results show that the proposed method has a good effect on the deployment of nodes with large differences in the sensor network.The nodes are evenly distributed,the overlapping coverage is low,the node utilization rate is 95%,and the coverage probability is above 99.0%.The proposed method effectively optimizes the deployment effect of network nodes and achieves the best coverage.
