Abstract
Sensing and analyzing moving objects is an important task for commanders to make decisions in Network-centric Warfare(NCW). Spatio-temporal queries are essential operations to understand moving objects situation. This paper proposed a new method for addressing distributed range querying moving objects problem, which was not considered in related studies. Firstly, the paper designed an index structure called MOI which utilized hilbert curve to mapping moving objects into 1-dimensional space and then used DHT to index. Then based on locality-preserved characteristic of hilbert curve, the paper devised a high-efficient spatio-temporal range query algorithm, which greatly reduces routing messages. Experimental results reveal that MOI outperforms other related algorithms and exhibits a low index maintaining cost.
