Environmental Evaluation and Regulation Method of Ancient Buildings Based on Wireless Rechargeable Sensor Network

Ancient buildings are precious historical and cultural heritage. Environmental evaluation and regulation can effectively protect ancient buildings. In view of this, a health monitoring network framework for ancient buildings based on wireless rechargeable sensor network (WRSN) is proposed. In this network, the battery capacity of these sensors used for data collection is limited. Therefore, to maximize the network lifetime, a heuristic algorithm based on dominating set is proposed. The algorithm can collect data through a minimum number of sensors and find an anchor set with a known set of all sensors deployed in the sensing domain. Then, the mobile devices accessing the anchor point are scheduled by the minimum dominating set (MDS) method and the proposed device scheduling algorithm (DSA). Meanwhile, the environmental evaluation and regulation method of ancient building is proposed. Finally, the simulation results show that the method can adjust and control the environmental data around the ancient buildings, and has a better performance.
