對於無線感測網路(Wireless Sensor Network)來說,覆蓋問題與存活週期一直以來都是重要的議題,如何有效的利用感測器有限的電量達到最長的存活週期並且同時保有可容許的覆蓋率為我們主要的目標。現有的相關文獻中,絕大部分的研究著重於二維的理想平面或是三維的全空間。然而實際的地形是凹凸崎嶇不平的,因此現有的解決方法無法得到較真實的結果,所以我們利用Spline Function[1]產生FoI (Field of Interest, FoI)[23][24]來建置具有起伏的三維地形。此外我們提出了EES演算法,在不同的時段當中將一部分的Sensor node當作中繼轉發節點,讓感測器間重疊感測的區域變少,以避免不必要的能量耗損,並且透過睡眠機制解決單一節點覆蓋半徑過大造成存活時間過短的問題,使得無線感測網路的整體存活時間增加並擁有相同的覆蓋率。在評價結果,我們所提出的算法提供了更高效的連接和高覆蓋率。
Coverage and connection problem have been the topic which worth exploring in wireless sensor networks (WSNs). How to effectively use the limited power to achieve the longest lifetime and keep acceptable coverage ratio are the major goals. Currently, some researchers have started to study this topic, but their proposed methods focused on 2D ideal plane or 3D full space. However, the actual terrain is rugged and uneven. Therefore, the exist solutions cannot obtain the fairest information. In order to solve this problem, we use the Spline Function [1] generated FoI (Field of Interest, FoI)[23][24] to build three-dimensional terrain. Furthermore, we propose the EES algorithm, which to select a part of the sensor nodes as the relay node at different epoch, hence the overlap areas between the sensor sensing range is reduced so that the unnecessary energy consumption can be avoided. Moverover, our proposed sleep mechanism can solve a shorter lifetime problem is causing by the coverage radius of a single node. In this way, it increasing the survival time of overall wireless sensor networks with acceptable coverage ratio. By the simulation results, the proposed algorithm indeed provides a more efficient connections and high coverage.
