无线传感器网络的一种多层数据融合方案

Scheme of multi-level data fusion for wireless sensor networks

对一种无线传感器网络路由协议定向扩散作了分析,并针对其局限性提出了一种多层数据融合方案。多层数据融合方案采用多层结构,在数据传输过程中建立节点的属性并进行父亲选择融合和数据分发。实验证明:多层数据融合方案较之定向扩散节约了50%的传输能量,而没有危及网络的可靠性和传输效率。

One of the protocol of the wireless sensor networks called directed diffusion is analyzed,and a scheme of multi-level data fusion is proposed aimed to the directed diffusion＇ s limit. The multi-level data fusion scheme with tiered structure built note＇s attribute,fusion father-select and divided data in the process of data transmitting. Experiments demonstrate that our enhanced scheme can save transmission energy up to 50% over directed diffusion ,without any reliability or delivery efficiency being compromised.
