摘要: 無線感測網路是一個新興的技術,藉由提供無所不在的偵測、計算與通訊的能力可以大大地便利我們的生活。然而,在設計許多實際的應用上要維持足夠的覆蓋並且延長系統的使用期是兩個互相矛盾的因素。在這篇論文中,我們提出一個分散式的機制可以讓多餘的感測器進入休眠模式以節省電源,而同時維持整個感測的區域在 k 層覆蓋上(k 是一個給定的值)。與 [7] 這篇作者提出的方法做比較,我們提出的方法有較低的複雜度。
The wireless sensor network is an emerging technology that may greatly facilitate our life by providing ubiquitous sensing, computing, and communication capability. However, to maintain sufficient coverage and achieve long system lifetime are two contradicting factors in the design of many practical applications. In this paper, we propose a distributed scheme that allows us to put redundant sensor nodes to sleep mode to save energy while maintain the sensing field sufficiently k-level covered, where k is a given parameter. Compared to an existing scheme [7], the proposed scheme has a smaller computational complexity.
