煤矿环境监测是无线传感器网络的一个重要应用，具有很大的商业潜力。我们讨论了一个结构感知的自适应无线传感器网络系统，SASA的设计。通过规范网状传感器网络的部署和制定一个合作机制的基础上定期信标策略，SASA是能够快速检测地下塌陷引起的结构变化。我们进一步开发了一个健全的和强大的机制，有效地处理查询不稳定的情况下。在一个真实的煤矿中部署了一个带有27个云母微粒的原型。我们提出了我们的实施经验以及实验结果。为了更好地评估SASA的可扩展性和可靠性，我们还进行了大规模的跟踪驱动的仿真实验收集的真实的数据的基础上。
Environment monitoring in coal mines is an important application of wireless sensor networks (WSNs) that has commercial potential. We discuss the design of a Structure-Aware Self-Adaptive WSN system, SASA. By regulating the mesh sensor network deployment and formulating a collaborative mechanism based on a regular beacon strategy, SASA is able to rapidly detect structure variations caused by underground collapses. We further develop a sound and robust mechanism for efficiently handling queries under instable circumstances. A prototype is deployed with 27 mica2 motes in a real coal mine. We present our implementation experiences as well as the experimental results. To better evaluate the scalability and reliability of SASA, we also conduct a large-scale trace-driven simulation based on real data collected from the experiments.
