Zhengxia and Laisheng (2010) presented a logistics monitoring
platform based on internet of things. The proposal used widespread
technologies, such as: EPC, RFID, GPS, GPRS, GSM and
WSN. The work introduced concepts about dynamic and static
EPC in order of reduce the data flow between client and server
devices. Furthermore, it could manage data regarding loads in a
simple and efficient way. The platform architecture had three layers:
Data Acquisition, Data Transport and Background Data
Processing. The Data Acquisition layer was in charge of getting information
about loads, through EPC and GPS technologies. According
to the EPC functions, every load can receive a unique EPC number.
However, the authors developed a static and dynamic EPC model,
which reduced the data flow and reused EPC numbers. The Data
Transport layer did the communication between components using
GPRS. The Background Data Processing received and processed the
loads information, storing in database. This layer provided information
about load history, statistics analysis and products reports.
Even more, it had alerts that inform when a product expired or it
was delayed.
