Abstract: We research into improving the quality of the reconstructed distribution from spatiotemporal monitoring data collected by mobile sensor network. Our approach is to attack the problem from the source, by mobilizing the sensors to harvest data of high information content so that the reconstructed distribution has minimum distortion. We consider four realistic constraints: limitations of wireless communications, limited supply of energy and sensor resources and difficult terrains. We treat each mobile sensor as an intelligent cooperative autonomous agent. Our simulation results show that cooperative-orbital algorithm outperforms others. It reduces an average of 738% (ranging from 625% to 885%) more error than mobile sensors deployed in Equally Distributed Grid and 35-314% more error than independent methods by consuming 74-81% lesser energy. Our method also has a resource utilization efficiency of 250 times that of static sensors. The results also show that our approach is stable and robust to non-ideal communications.
