| 摘 要： | 针对无线传感器网络中传感节点能量的有限性和无线链路的时变性，设计了一种高能效的、适应性强的安全数据融合算法EASDA。该算法在融合过程中基于非物理意义的模式码将传感器节点分成冗余集，在数据传输过程中利用数字喷泉码进行编码。仿真结果显示，该算法有效地减少了冗余数据的传输，使网络中能耗更加均衡，并且适应于任何删除信道。

| Abstract: | Due to the limited energy of sensors and the time-variation of wireless channels in wireless sensor networks, this paper proposed an efficient and adaptable secure data aggregation protocol for WSNs.It classified sensor nodes into different redundancy sets based on pattern codes without physical meanings, and applied digital fountain coding to data transmission. Simulation results show that the proposed protocol can reduce the redundant data transmission, balance energy consumption in network, and is adaptable for any erasure channel. |

| Keywords: | time-variation pattern code digital fountain code erasure channel secure data aggregation |
