摘要: 无线传感器网络是能量受限型网络,提高能量效率、延长网络寿命是无线传感器网络设计的重要目标。为了延长设防区域无线传感器网络寿命,并且确保无线传感器网络能够检测到入侵目标,提出利用一种圆环状的辐射扫描波来检测入侵目标。通过理论分析和仿真,结果表明,警戒系统使用辐射扫描算法的网络寿命比周期休眠算法更长。

Abstract: Wireless Sensor Network(WSN) is a kind of energy constrained network,with improving energy efficiency and prolonging network lifetime as the significant goal.This paper proposes a kind of diffusive scan waves of sensing activities,which is used to detect the target,to prolong the lifetime of the WSN in the outpost area,and to ensure that the WSN can detect the invasion of target.Through theoretical analysis and simulation,it is shown that a surveillance system,using diffusive scanning algorithm,has longer lifetime than sleep cycling algorithm.
