摘要

在无线传感器网络应用中，大量传感器节点被部署到远程位置，长时间无人值守。当电池供电的传感器节点耗尽其能量时，它被认为是“死”的，在大多数应用中，充电或更换电池是不可能的。无线传感器网络的寿命取决于可用的有限能量的有效利用。本文研究了线性无线传感器网络作为无线传感器网络的一个子类在铁路监控中的应用。本研究的目的是展示适当的节点部署对延长线性无线传感器网络寿命的影响。结果表明，该部署方案降低了LWSN的能耗，提高了网络的使用寿命。

The effect of node deployment scheme on LWSN lifetime for railway monitoring applications

A large number of sensor nodes are deployed to remote locations and left unattended for a long time in wireless sensor network applications. When a battery-powered sensor node depletes its energy, it is assumed as “dead” and recharging or replacing the battery is not possible in most of the applications. Lifetime of the wireless sensor network depends on the efficient use of available restricted energy. Railway monitoring application of Linear Wireless Sensor Networks (LWSNs) which are a subclass of wireless sensor networks is considered in this paper. The objective of this study is to present the effect of proper node deployment in extending the linear wireless sensor network lifetime. Thanks to proposed deployment scheme, it is shown that the energy consumption of the LWSN is lowered and thus the lifetime of the network is increased.
