我们表明，一个无线传感器网络系统可以专门设计一组复杂的部署要求和约束。解决的设计问题包括：应对北极冬季的低功耗设计和科普通信故障的自适应行为。这些技术已于2008年由Glasweb团队在冰岛的一个WSN部署中实现。本文展示了这如何使基站首次度过冬季。这些系统不是扩大电源来科普，而是缩小它们的活动，特别是通信和dGPS传感。类似地，不是过度设计无线电网络，而是使用大型多级缓冲器来管理断开时段。2008年主要部署后采用的技术提高了总体成功率。该系统由八个冰下传感器节点组成，连接到冰川上的基站和山腰上的固定参考站。
We show that a wireless sensor network system can be designed specifically for a set of complex deployment requirements and constraints. Among the design issues tackled are: low power design which copes with arctic winters and adaptive behaviour to cope with communications breakdowns. These techniques were implemented in a WSN deployment in Iceland in 2008 by the Glacsweb team. This paper shows how this has allowed base stations to survive the winter for the first time. Rather than scaling up the power sources to cope, the systems scale-back their activities, especially communications and dGPS sensing. Similarly instead of overdesigning the radio networks, disconnection periods were managed using large multi-level buffers. The overall success was increased by techniques introduced after the main deployment in 2008. The system is comprised of eight subglacial sensor nodes, connected to a base station on the glacier and a fixed reference station on the mountainside.
