节能是无线传感器网络中的一个重要问题，人们对无线传感器网络的节能进行了大量的研究。然而，这些研究中的大多数都集中在收集信息时节省电力。在本文中，我们解决了无线传感器网络中的能量有效的信息传播问题。我们提出了一种在无线传感器网络中传播信息的同时优化电力消耗的方法。我们的新传播方法采用泛洪，并使用接收器信号强度来确定广播时间。在我们的方法中，离发送节点最远的节点将首先重新广播消息，并且当预定广播的节点从其他节点接收到预定消息的副本时，广播被取消。我们评估我们提出的方法通过模拟。结果发现，在整个网络中，建议方法的电力消耗最大是泛洪方法的三分之一。此外，我们表明，无线电波的传输距离越远，我们的方法可以更有效地传播信息到网络。
Power-saving is one of the important issues in wireless sensor networks and many studies on power-saving in wireless sensor networks have been done. However, most of these studies have focused on saving power in gathering the information. In this paper, we tackle the issue of the energy-efficient information dissemination in wireless sensor networks. We propose method of disseminating information while optimizing electric power consumption in wireless sensor networks. Our new dissemination method employs flooding and uses the receiver signal strength to determine the broadcast timing. In our method, the node farthest from the sending node will rebroadcast the message first and a broadcast is canceled when a node scheduled to broadcast receives a duplicate of the scheduled message from other nodes. We evaluate our proposed method by simulation. As a result, it is found that the electric power consumption of the proposal method in the entire network is one-third that of the flooding method at the maximum. Furthermore, we show that the farther the transmitting distance of the wireless radio wave becomes, the more efficiently our method can disseminate information to the network.
