摘要
首先对无线传感器网络数据融合的相关技术进行比较,在分布式数据融合算法的基础上提出了一种改进高效数据融合算法,利用NS2仿真平台对其传输开销进行仿真测试。仿真结果表明,相比分布式数据融合算法,所提的算法能够更有效地减少传输开销并且节省节点能耗。
The related key technologies of Wireless Sensor Networks （WSNs） secure data aggregation was compared. Then an effective data aggregation algorithm（EDAA） was proposed after the distributed algorithm in data aggregation was analyzed. The algorithm was simulated in NS2 software, and the result shows that the data aggregation algorithm EDAA can effectively reduce the transmission costs and the energy consumption of nodes.
