无线传感器网络中节点的动态部署

作为无线传感器网络中节点部署的新兴技术，动态部署得到了越来越多的重视并在近年来取得了理论和应用上的一系列进展。首先介绍了动态部署的基本概念和设计难点，并根据移动主体的不同，将动态部署分为节点自主部署和机器人辅助部署两种方式。然后，依据静态和动态两种部署场景，分类论述了节点自主部署的代表性成果。接着从网络构建和网络维护两个阶段介绍机器人辅助部署的主要方案。最后总结了节点动态部署亚待解决的问题，并探讨了进一步研究的方向。

Dynamic Deployment of Nodes in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) is a self-organized network consisting of multiple sensors with limited resources. One fundamental issue in WSNs is deployment of nodes which reflects the networks construct costs, coverage quality, topology and routing etc. As a new technology, dynamic deployment of nodes makes WSN more applicable in many scenes. hhis paper first introduced the self dynamic deployment of nodes with recent valuable theories and algorithms,which are focused on uniform distribution of nodes. And then typical robot assistant deployment strategies were described according to different phases of WSN, which arc aimed at robot movement control and network maintenance.More specifically, advantages and disadvantages of these algorithms were summarized. Finally, key design points and future research directions were put forward.
