摘要
针对无线传感器网络中节点能量有限的特点,将一种数据集成算法引入无线传感器网络,通过去除节点间的冗余信息来降低网络中的数据流量,从而降低网络能耗,达到提高网络能量利用率和延长网络寿命的目的。以树型无线传感器网络为例,分别对采用数据集成算法前后的网络能量消耗进行分析,并给出了相应的能量消耗模型。通过计算机仿真和实验数据监测的方法,验证了此数据集成算法在降低树型WSN能耗中是有效的。
Aiming at the characteristics of limited nodes energy in wireless sensor networks, the data integration algorithm is introduced into wireless sensor networks. By removing redundant information in sensor nodes to decrease the data flow of network, the energy consumption of the network is reduced, and the goals of improving energy utilization rate and lengthening life- time of network are achieved at the same time. The research foundation is the tree structure WSN. The energy consumption of network is analyzed and researched before and after data in- tegration, and the corresponding energy consumption mode is given. Followed by the ways of computer simulation and experimental data monitoring, the papers proves the data integration is effective in reducing energy consumption of network.
