在本文中，我们提出了一种新技术，用于在水下传感器网络监控的水下环境中定位感兴趣的事件。我们不是像所有提出的技术那样主动定位网络中的每个节点，而是从反应的角度来定位。我们将定位问题简化为寻找4节点覆盖的问题。每当节点检测到事件时，使用锚节点来反应性地定位该节点，并且向宿提供必要的信息。通过限制传感器节点的感知范围，一旦我们获得了检测到事件的节点的位置，我们就可以粗略估计事件的位置。我们表明，在能源消耗方面，这种本地化技术远远超过其他。
In this paper, we present a novel technique for localising an event of interest in an underwater environment monitored by an underwater sensor network. Instead of proactively localising every single node in the network as all proposed techniques set out to do, we approach localisation from a reactive angle. We reduce the localisation problem to the problem of finding 4-Node Coverage. Whenever a node detects an event, it is reactively localised using the anchor nodes, and the sink is supplied with the necessary information. By limiting the sensing range of the sensor nodes, once we have obtained the location of the node that has detected the event, we have a rough estimation of the location of the event. We show that in terms of energy consumption, this localisation technique far surpasses others.
