无线传感器网络中覆盖性问题的研究

无线传感器网络由大量的具有低能量,短寿命并且不可靠的传感器节点组成,因此在设计无线传感器网络时一个主要的目标在于保证足够的覆盖率以及能量可靠性的前提下可以延长网络的寿命。本文介绍了几种减少能量消耗以延长网络寿命的节点调度方法,并比较了各种方法的优缺点,指出其应用环境和需要进一步研究的工作。最后在这几种算法的基础上提出了一种新的算法。

Research on Coverage-preserving Issue in Wireless Sensor Networks

Wireless sensor network consists of a large number of low-power, short-lived, unreliable sensors. One of the main objectives is to obtain long system lifetime, as well as maintain sufficient sensing coverage and energy reliability. This paper presents some node-scheduling schemes which can increase system lifetime by reducing system overall energy consumption. Furthermore, we compare them, and address where each solution could be used and future work should still go on. At last, we put up a new scheme based on these schemes.
