基于星型传感器网络的支持多种查询的分布式交通移动对象索引

Distributed Traffic Moving Object Index Based on Star Sensor Network Supporting Multiple Queries

笔者提出一种新的基于分布式的移动对象索引DMQI,针对星型拓扑结构的传感器网络特点,从对象和时空范围2个维度出发,有效管理移动对象历史和当前位置信息,高效支持对历史和当前数据信息的对象查询和范围查询,并根据索引设计合适的更新查询算法。

This paper presents a new distributed object index DMQI,which is based on the characteristics of the sensor network of the star topology,from the two dimensions of the object and the space-time range,effectively manages the moving object history and current location information,and efficiently supports object query and scope query of the history and current data information,and design appropriate updated query algorithm according to the index.
