无线传感器网络越来越多地在工业中部署，以确保关键设备的安全并提高制造车间的产量。这些网络中的传感器设备被编程为频繁发送数据和/或报告感兴趣的事件。本地化可以精确定位此类事件的来源，还可以查询特定位置的设备。但是，这种本地化设备的过程对动态网络拓扑提出了挑战。同样，网络拓扑也对动态网络提出了挑战，因为网络拓扑会影响性能、网络成本和网络速度。在无线传感器网络中保存整个网络节点及其链路的信息是一项具有挑战性的任务。在本文中，我们提出了一种高效快速的定位方案，旨在处理网络拓扑的动态变化，以及每当拓扑发生变化时处理网络拓扑信息的建议。所提出的方案的使用可以仅限于新节点加入，从而实现快速定位，或者可以用作成熟的定位机制。所提出的方案显着降低了定位和拓扑状态所需的开销和时间。
Wireless sensor networks are increasingly deployed in industries for ensuring the safety of critical equipment and to boost production on manufacturing floors. The sensor devices in these networks are programmed to frequently send out data and/or to report events of interest. Localization allows to precisely locate the origin of such events and also to query devices of a specific location. But, this process of localizing devices poses a challenge in a dynamic network topology. Similarly, Network topology also poses a challenge in a dynamic network as network topology impacts performance, cost of the network and speed of the network. To keep information of the whole network nodes and their links in a wireless sensor network is a challenging task. In this paper, we present an efficient and fast localization scheme designed to handle dynamic changes in network topology as well as a proposal to handle information of network topology whenever topology changes. The usage of the proposed scheme can be restricted to new node joins enabling fast localization or can be used as a full-fledged localization mechanism. The proposed scheme significantly lowers the overhead and time required for localization and topology status.
