英文摘要： Being time-saving and easy in installation, convenient in setting up a network and low in cost, wireless sensor networks have broad application prospects in the field of deformation monitoring. However, wireless sensor nodes are characterized by limited computing power, energy and transmission bandwidth, so there are still problems to be solved if large scale applications are desired. The project carries out a study on the theories and technologies of employing wireless sensor networks in deformation monitoring, focusing on such key issues as clock synchronization, data compression, data transmission and data processing. By combining the methods of theoretical analysis, experiments, simulation and practical tests, the supply and demand model for clock synchronization accuracy is established and the corresponding mechanism for clock synchronization is realized. On the basis of revealing the degree of temporal and spatial correlations in the monitoring data, distributed algorithm of data compression which can be applied in wireless sensor network is explored. Through different types of monitoring data, highly efficient and reliable multi-hop data transport protocols in wireless sensor networks will be designed and realized. Combining the features of different types of monitoring data, collaborative data processing will be conducted to improve the reliability of the monitoring result. The research results will address key theoretical and technical issues in deformation monitoring based on wireless sensor networks. And they can have positive effects in expanding wireless sensor networks applications.
