摘要翻译：
我们认为无线传感器网络由多个协作节点组成，每个协作节点都能适应流式数据进行最小均方估计，同时保持相邻节点之间的信息交换以提高性能。为了减少通信开销，延长通信寿命，同时保持扩散协作的优点，我们提出了一种能量有效的扩散策略，该策略采用基于事件的通信机制，允许节点在必要时与邻居协作。我们还研究了该算法的性能，证明了其网络平均误差和MSD在稳态下是有界的。数值结果表明，该方法在不显著牺牲稳态网络MSD性能的前提下，有效地降低了网络能耗。

英文摘要：
  We consider a wireless sensor network consists of cooperative nodes, each of them keep adapting to streaming data to perform a least-mean-squares estimation, and also maintain information exchange among neighboring nodes in order to improve performance. For the sake of reducing communication overhead, prolonging batter life while preserving the benefits of diffusion cooperation, we propose an energy-efficient diffusion strategy that adopts an event-based communication mechanism, which allow nodes to cooperate with neighbors only when necessary. We also study the performance of the proposed algorithm, and show that its network mean error and MSD are bounded in steady state. Numerical results demonstrate that the proposed method can effectively reduce the network energy consumption without sacrificing steady-state network MSD performance significantly.
