【摘要】 对事件数据融合策略进行改进,提出一种新的基于汇集环的数据融合路由策略,论述策略的各个方面,包括路由的形成、汇集环停留的时间比例等,并对策略性能进行分析,最后通过实验予以验证。研究结果表明:在网络的非hotspots建立环绕网络的汇集环,除第1环数据直接发往Sink外,其他环的数据由汇集环融合后再发往Sink,极大地减少了需要发往Sink的数据量,成倍地提高了网络寿命,验证了该策略的有效性。更多还原

【Abstract】 A new event routing approach based on aggregation ring was proposed to improve the performance of event data aggregation method. The proposed scheme discussed the establishment of route path, the ratio of staying time of ring and the performance. An aggregation ring was established in non-hotspots. The results show that all data except the 1st ring route to ring aggregate in the ring, and then sent to the Sink. Thus the amount of data need to be sent to the Sink is greatly reduced, and the network lifetime can be improved greatly, which verifies the effectiveness of the proposed scheme.更多还原
