【Abstract】 In order to improve the timeliness of the information transmission of flood disasters,the information transmission technology has low success rate,long information transmission delay and high information transmission energy consumption. Real-time transmission technology for demand information of flood disasters. Calculate the energy perception threshold of the cluster head and the remaining nodes in the cluster in the cluster node of the constructed remote sensing network,and complete the corresponding cluster head node and region update according to the obtained threshold and update constraint conditions,according to the bandwidth of the remote sensing network and the cluster node of the next hop The energy consumption is divided into information,and the segmented group information is transmitted by parallel transmission. Combined with the multi-scale cooperative mutation mechanism,the particle swarm optimization algorithm is used to optimize the information transmission path,and the optimal path is used to realize the real-time transmission of the disaster point demand information. The experimental results show that the proposed information transmission technology has higher information transmission success rate and shorter transmission delay than the current disaster point information transmission technology,and the transmission success rate and delay are less affected by the information transmission rate change. The information transmission energy consumption is significantly lower than the two information transmission technologies of the experimental comparison.更多还原
