Sensor node deployment for large-scale wireless sensor networks

无线传感器网络已经引起了广泛的关注。传感器节点的初始物理位置对无线传感器网络的性能有很大的影响。在这项研究中，我们提出了一种新的部署方法的传感器节点，当大量的节点分布从空中的监测区域，是从地面无法访问。在我们的部署方法中，每个传感器节点都配备了一个降落伞和一个设备，以在空中的两个下降行为之间切换。传感器节点从空中跌落后，随机协调跌落行为，使其均匀分布在监测区域内。通过模拟评估，我们证实了我们的建议可以实现高度的均匀性，在放置的节点。

Wireless sensor networks have attracted a great deal of attention. The performance of wireless sensor networks is greatly influenced by the initial physical placement of the sensor nodes. In this research, we proposed a novel deployment method for sensor nodes, when a large number of nodes is distributed from the air in a monitoring region that is inaccessible from the ground. In our deployment method, each sensor node is equipped with a parachute and a device to switch between its two falling behaviors in the air. After being dropped from midair, sensor nodes stochastically coordinate their falling behavior in order to distribute themselves uniformly in the monitoring region. Through simulation evaluations, we confirmed that our proposal can achieve a high uniformity in the placement of the nodes.
