There are several shortages when searching a sensor entity by the traditional search engine.To overcome these problems,an IoT-oriented sensor entity search system was designed and implemented.By adopting the multithreading technique and following regular matching rules,the original information database was established.Combining Lucene scoring mechanism with the geographic location property that sensor entities were generally equipped with,a sorting algorithm based on the distances between sensors was proposed,which made the information retrieving of the system efficient.Moreover,the retrieved results were dynamically displayed on the Google map utilizing the Google Maps API,while the sensor data were updated in real time using the AJAX technique.The experimental results indicate that compared with the traditional search engine,the proposed system can not only improve the query accuracy,but also bring better user experience.
