RelicNet: highly reliable wireless sensor system for microclimate monitoring in wildland cultural heritage sites
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.
