Warehouse is an important part of logistics which becomes a hot research topic. However, the existing warehouse management system has exposed certain technical weakness. In this paper, an adaptive communication framework of the warehouse management system based on RFID (radio frequency identification) and WSN (wireless sensor networks) was proposed. Three forms of network architecture that combines RFID and WSN technologies are deeply analyzed and contrasted. The concept of group procedure is introduced. A novel improved network architecture based on the method of group procedure is proposed and its features in self-organization, feasibility, technical challenges are discussed thoroughly.
