一种基于目标圆的有向强栅栏构建算法
A Construction Scheme for Directional Barrier Based on Target Circle
摘要
Abstract
K-barrier coverage is one of the hot spot in directional wireless sensor network. This paper proposes a dis⁃tributing directional barrier construction based on target circle(DBCTC). Two novel models:target circle and ener⁃gy consumption ratio are created for the first time. The center of target circle is just the point with maximum X coor⁃dinate within the sensing region of the preceding node. Its radius is always the sensing radius. The energy consump⁃tion ratio is the ratio of actuating energy consumption to barrier gain. Target location is determined by target circle. The mobile node with minimum energy consumption ratio moves to target next node location. Simulation results show this method could decrease 60%energy consumption than other method.关键词
