A node deployment strategy for efficient sensing with mobile sensors in sparse sensor networks

Abstract

In this paper, we propose an extended method of our previous mobile sensor control method, named DATFM (Data Acquisition and Transmission with Fixed and Mobile node). DATFM uses two types of sensor nodes, fixed node and mobile node. The data acquired by nodes are accumulated on a fixed node before being transferred to the sink node. The extended method, named DATFM/DF (DATFM with deliberate Deployment of Fixed nodes), strategically deploys sensor nodes based on the analysis of the performance of DATFM in order to improve the efficiency of sensing and data gathering. We also conduct simulation experiments to evaluate the performance of DATFM/DF.
