The motivation for writing this book came from our previous research works on sensor
coverage. They received a large number of citations and this number grows rapidly each …

Sweep coverage plays an important role in many applications such as data gathering,
sensing coverage and devices control. In this paper, we deal with the cooperative sweep …

With the increasing demand for security, building strong barrier coverage in directional
sensor networks is important for effectively detecting un-authorized intrusions. In this paper …

A region is a belt if its boundary consists of two parts such that every point in one part has
equal distance to the other part. This distance is called width and these two parallel …

防禦線覆蓋問題(barrier coverage problem) 在無線感測網路中是一項非常重要的課題.
在本論文中, 我們將探討一個新形態的防禦線覆蓋問題, 其名稱為強化防禦線覆蓋問題 …

Aiming at the repair of barrier coverage gap in wireless sensor networks in three-
dimensional environment, a clustered barrier gap repair algorithm (Gap repair algorithm of …

In the past years, wireless sensor networks (WSNs) have increased successful real-world
deployment in a wide range of civil and military applications. In order to ensure effective …
