【摘要】 研究了无线传感器网络中一种基于历史数据分组的感知查询技术,提出了对传感器节点属性进行有效分组的策略.依据各个组构建相应的森林,并提出了基于森林的聚集技术和加速聚集技术.同时提出了分组和森林的调整策略,以确保基于森林的聚集技术的有效性.最后,通过实验证明了所提方法的正确性、有效性和实时性.更多还原

【Abstract】 Presented and discussed in this paper are acquisition queries based on constructing teams using historical data,and the policy of making effective teams based on sensor’s attributes.Each team is then mapped into a forest.Two forest-based aggregation techniques,namely forest-based aggregation technique (FBAT) and forest-based accelerated aggregation technique(FBAAT),are proposed.In addition,an adjusting policy in consideration of wireless networks’ real-time nature is proposed to make the two techniques more effective.Finally,experiments are carried out to prove these techniques’ feasibility, validity and real-time nature.更多还原
