文摘

Study distributed data management from big data trajectory based on distributed R-tree. The query trajectory is based on distance threshold and activities involved in the trajectory. The algorithms to store and maintain data into distributed index achieve efficiency and effectiveness. The algorithm to answer to the trajectory query achieves efficiency and effectiveness of the query. Experimental results demonstrate that our index achieve a high scalability, stability and fault tolerance.
