【摘要】 提出了RelicNet:面向野外文化遗址微气象环境监测的高可靠无线传感系统。RelicNet将整个系统组织为一个多网融合的延迟容忍网络(DTN,delay-tolerant network),并提供了跨层次数据可靠性维护框架以确保数据传输中每个步骤的可靠性。系统目前已部署在地处戈壁沙漠的著名野外文化遗址——敦煌莫高窟中,共计241个传感器节点覆盖了莫高窟57个典型洞窟。利用系统所得到的数据对洞窟内微气象环境变化规律进行了分析,并通过网络和电池性能测试验证了系统的可靠性和长寿命。更多还原

【Abstract】 RelicNet, highly reliable wireless sensor system for microclimate monitoring in wildland cultural heritage sites was proposed. RelicNet organized the whole system as a multi-tiered delay-tolerant network (DTN), and provided a cross-tier data reliability maintenance framework to ensure the reliability of each step of data delivery. The currently de- ployed system consists of 241 sensors covering 57 typical caves of the Mogao Grottoes, a well-known wildland cul- tural heritage site in the Gobi desert. The microclimate change patterns in caves were analyzed using the data col- lected by the system, and the reliability and long lifetime of the system were verified through network and battery performance evaluations.更多还原
