摘要：In this paper, we propose DATFM/DA (Data Acquisition and Transmission with Fixed and Mobile node with Deployment Adjusting), which is an extension of our previous mobile sensor control method, DATFM. DATFM/DA uses two types of sensor nodes, fixed node and mobile node . The data acquired by the nodes are accumulated on a fixed node before being transferred to the sink node. DATFM/DA divides the target region into multiple areas, and statically deploys mobile nodes to each divided area. In addition, DATFM/DA adjusts the number of mobile nodes deployed in each area based on the analysis of the performance. We also conduct simulation experiments to verify that this method further improves the performances of sensing and data transfer.
