【摘要】 节约能源是传感器网络面临的一个核心问题。针对传感器网络中数据冗余度较高的特点,设计了在传感器网络协议栈中建立数据融合层,通过减少网络中的数据包传输数目,达到降低网络能耗、延长网络生存时间的目的。并在传感器网络操作系统TinyOS上对数据融合层进行了实现。最后通过性能分析,验证了数据融合层的功效。更多还原

【Abstract】 Saving energy is a key problem in the wireless sensor network(WSN).According to high redundancy of data in WSN,the paper designs a layer of data aggregation.It is used to reduce the energy consumption of WSN and extend WSN’s survival time by decreasing the transmission of data packages in WSN.It realizes data aggregation layer on the platform of TinyOS.TinyOS is a wireless sensor network operating system.In the end,the data aggregation layer’s performance shows it is feasible.更多还原
