求翻译：良好的网络连通度和对传感区域的完全感知覆盖是传感网络能够正常工作的必要条件，也是部署传感器节点时需要考虑的关键问题，当前也已取得了很好的研究进展。如伯明翰大学的Yong Xu和Xin Yao考虑了具有障碍的检测区域，提出了一个新的遗传算法来优化满足覆盖的最少传感器的部署[7]。Shu Zhou等通过在已有网络中添加少量移动传感器，结合动态规划算法有效地提高了网络连通度，并用最小的代价实现网络重构[8]。是什么意思？

Full perception of good network connectivity and sensing area coverage is a necessary condition of the sensor network to work properly, need to consider the key issues is also the deployment of sensor nodes, the current has also achieved good progress. Such as the University of Birmingham yong xu xi

Good network connectivity, and the sensing area of the sensor is sensing network coverage to be able to work properly, it is also necessary for the deployment sensor nodes need to be taken into consideration when the key issue, the current has also been made very good progress of the study.
