一种无线传感器网络的节点救援系统和方法,其中该方法包括步骤:当前网络节点获取下一转发节点的能量信息;根据能量信息判断下一转发节点是否出现能量危机;当出现能量危机时,当前网络节点通过主干网络搜索救援节点;当搜索到救援节点时,向救援节点发送救援信息,占用救援节点;根据救援信息,救援节点移动至发送救援信息的网络节点的通信范围内,代替下一转发节点进行数据通信。该方法能够在无线传感器网络中的关键节点出现能量危机时,迅速调动救援节点移动至该关键节点,来代替该关键节点进行数据通信,以提高无线传感器网络中数据传输的可靠性。
A node rescue system and method for a wireless sensor network, wherein the method comprises the steps of: the current network node obtaining energy information of a next forwarding node; determining whether there is an energy crisis in a next forwarding node according to the energy information; when an energy crisis occurs, The network node searches for a rescue node through the backbone network; when the rescue node is found, it sends rescue information to the rescue node and occupies the rescue node; and according to the rescue information, the rescue node moves to the communication range of the network node that sends the rescue message instead of the next transfer Node for data communication. The method can rapidly move the rescue node to the key node when there is an energy crisis in the key nodes in the wireless sensor network to replace the key node for data communication so as to improve the reliability of data transmission in the wireless sensor network.
