Abstract：
In recent years, with the development of a new generation of information and communication technologies, especially the development and application of modern sensors, wireless Internet of Things, and big data technologies, early identification, automatic monitoring, and early warning of hidden geological hazards have become mainstream technical means. Landslide disaster monitoring is an important and practical direction of Internet of Things technology in a disaster monitoring system, which has the advantages of low cost and mature technology. With the continuous development of the Internet of Things technology, standardized data sharing and interoperability have been put forward on the agenda. Based on the OGC Sensor Thing API standard, this article analyzes landslide monitoring data sharing and interoperability from the data model, shared service content and system construction, and provides a reference for the standardization of geological disaster data sharing and interoperability based on the Internet of Things technology. Due to the characteristics of a simple layout, strong anti-damage and self-healing ability. Self-organization, etc., based on the Internet of Things technologies such as ZigBee multi-sensor and wireless Mesh network, it is widely used in the data collection and transmission of geological disaster monitoring systems. The experimental analysis is carried out based on various parameters namely computational cost, power utilization, fitness function, danger rate, evacuation time, total travel time as well as root mean square error. Finally, the results conclude that the proposed approach attained better performances in terms of cost, power utilization and error rate.
