Abstract

In this paper we discuss topology design and dimensioning of sensor networks to achieve full sensing coverage. We consider two ways of deploying the sensors, placing them according to some regular pattern or scattering them randomly, and two ways of activating the sensors, optimally according to some predefined schedule or randomly, when each sensor follows a wake-up schedule independently from the other sensors. We provide analytic expressions for the necessary and sufficient number of sensors that guarantee coverage in these scenarios and determine the cases when deterministic sensor placement or optimal sensor activation can achieve significant gains. We consider sensing with bounded delay and show that the number of sensors to be deployed can be decreased significantly even at low sensing delays.
传感器网络中确定性布局和协调激活的增益
在本文中,我们讨论了传感器网络的拓扑设计和尺寸,以实现全传感覆盖。我们考虑了两种部署传感器的方法,一种是按照规则的模式放置传感器,另一种是随机地分散传感器;另一种是在每个传感器独立于其他传感器遵循唤醒时间表的情况下,按照预定的时间表或随机地激活传感器。我们提供了必要和足够数量的传感器的解析表达式,以保证在这些场景中覆盖,并确定确定性传感器放置或最佳传感器激活可以获得显着收益的情况。我们考虑具有有限延迟的传感,并表明即使在低传感延迟下,部署的传感器数量也可以显着减少。
