A Real-Time Monitoring and Statistic System Using Hierarchical Sensor Network

In many occasions, the usage situation of some rooms needs to be reported to users timely, such like libraries, study halls, cafeterias, etc. Usually the room resources are limited, so it is not reasonable if some rooms are overcrowded while some empty. This work aims to design a hybrid sensor network system to real-time monitor the usage situation of the rooms, so the users are able to keep timely information, thereby saving more time for everyone. The system has good scalability and ease of serviceability, adaptability, low cost, and simple promotion with a wide range of applications.
