保证稀疏覆盖的传感器调度

Scheduling Sensors for Guaranteed Sparse Coverage

Swaminathan Sankararaman, Alon Efrat, Srinivasan Ramasubramanian, Javad Taheri

摘要:

传感器网络特别适用于跟踪运动中的对象。对于这样的应用,只要未被覆盖的区域不是太大,则整个区域可以不需要被传感器覆盖。这个概念已经被Balasubramanian等人形式化为$κ$ -弱覆盖问题。该覆盖模型提供了关于对象可能在其中移动而未被检测到的区域的保证。在本文中,我们分析了该问题的理论方面,并提供了可实现的使用寿命的保证。我们介绍了一些实用的算法,并分析了它们的意义。主要贡献是一种新的线性规划算法,提供了接近最佳的寿命。通过大量的实验,我们分析了这些算法的性能的基础上定义的几个参数。

英文摘要:

Sensor networks are particularly applicable to the tracking of objects in motion. For such applications, it may not necessary that the whole region be covered by sensors as long as the uncovered region is not too large. This notion has been formalized by Balasubramanian et.al. as the problem of $κ$-weak coverage. This model of coverage provides guarantees about the regions in which the objects may move undetected. In this paper, we analyse the theoretical aspects of the problem and provide guarantees about the lifetime achievable. We introduce a number of practical algorithms and analyse their significance. The main contribution is a novel linear programming based algorithm which provides near-optimal lifetime. Through extensive experimentation, we analyse the performance of these algorithms based on several parameters defined.
