摘要
无线传感器网络栅栏覆盖研究已取得丰厚成果。提出一种巡逻式栅栏调度算法,该算法将栅栏均匀分为若干子栅栏,依次轮流激活子栅栏,激活的子栅栏工作一段时间后进入休眠状态,然后下一条子栅栏由休眠进入激活状态。因此子栅栏的轮流激活形成了栅栏的巡逻状态,当入侵者穿越栅栏时有很大概率会被巡逻子栅栏检测到。在确保栅栏检测率的情况下使得栅栏的生存时间得到大幅度延长。文中计算了在理论情况下的栅栏检测率,最后通过实验验证了该算法的准确性和可靠性。
The research of barrier coverage of Wireless Sensors Networks has achieved rich results. We proposed a patrol barrier scheduling algorithm,in this algorithm the barrierwas divided into several sub-barriers,and took turns to be activated; the activated sub-barrier would enter a dormant state after working a period,and then the next sub-barrier by dormancy into the activated state. So the sub-barrier activation in turn form the fence patrol state,when the intruder through the fence would be a great probability patrol fence is detected. Under the condition of ensure the detection rate of barrier made barrier greatly prolong survival time. In this paper,we calculated the theory in the case of barrier detection rate,finally the veracity and reliability of the algorithm is verified by experiment.
