传感器网络中引入位置信息的层次化低功耗技术

Hierarchical Low Power Consumption Technique with Location Information for Sensor Networks

Susumu Matsumae, Fukuhito Ooshita

摘要:

在由电池供电的传感器节点组成的无线传感器网络中,如何节省节点的功耗是一个主要问题。解决这个问题的通常方法是只激活必要的节点(例如,组成骨干网的那些节点),并使其它节点休眠。使用位置信息的一种这样的算法是GAF(地理自适应保真度),并且GAF被增强为HGAF(分层地理自适应保真度)。在本文中,我们表明,我们可以进一步提高HGAF的能量效率,通过修改的方式划分传感器领域。我们还提供了一个理论界对这个问题。

英文摘要:

In the wireless sensor networks composed of battery-powered sensor nodes, one of the main issues is how to save power consumption at each node. The usual approach to this problem is to activate only necessary nodes (e.g., those nodes which compose a backbone network), and to put other nodes to sleep. One such algorithm using location information is GAF (Geographical Adaptive Fidelity), and the GAF is enhanced to HGAF (Hierarchical Geographical Adaptive Fidelity). In this paper, we show that we can further improve the energy efficiency of HGAF by modifying the manner of dividing sensor-field. We also provide a theoretical bound on this problem.
