中文摘要：

为了减少数据汇聚的通信开销，提出一种基于簇分割的无线传感网数据汇聚方案，将簇划分为3个分区，为每个分区指定报告点，分区内与报告点具有相同读数的传感器在数据汇聚时不进行数据发送，减少了簇内数据传输量。分析与实验结果表明，该方案中簇内汇聚所需的通信量低于相关方案，在数据冗余度较高的情况下通信开销下降较为明显。

英文摘要：

For reducing the communication overhead of data aggregation, a cluster division based data aggregation scheme for wireless sensor networks in which the cluster is divided into three subareas and some report nodes are assigned to each subarea. The nodes which have same reading and located in same subarea with the report node will keep silent in data aggregating, thus the inner-cluster transmissions is reduced. Analysis and experiments show that the transmissions of inner-cluster data aggregation of our scheme lower than that of related schemes and the decrease of transmissions is obviously when the redundancy of sensor readings is high.
