无线传感网中一种改进的层次数据融合策略

Improved Level Data Aggregation Strategy for Wireless Sensor Networks

在无线传感器网络中，数据融合是减少能量消耗的有效途径。本文针对多层数据融合方案的局限性提出了一种改进策略。该策略是在已建立的每一层上再划分为两个子层，数据在邻层的相应子层中传输，避免了节点之间能量消耗不均，延长了网络的生存周期。

An improved strategy of level data aggregation is proposed for the limit of multi-level data aggregation scheme in this paper for Wireless Sensor Network. The strategy is divided each level into two sub-levels,transmitted the data between the adjacent two sub-levels,avoided unbalanced energy consumption of nodes and extended the network lifecycle.
