Based on the requirement of the transmission of real-time service in wireless sensor networks, the paper studies Weighted Fair Queuing (WFQ) algorithm profoundly. Having analyzed the reason why WFQ can't ensure the quality of real-time service, it proposes P-WFQ, which is a priority-based Weighted Fair Queuing (P-WFQ) algorithm. With sliding windows, P-WFQ combines WFQ and the priority-based mechanism...
In the supply chain management,the warehouse management is an important component.It is necessary to improve storage management efficiency and reduce operational costs and error rates.Therefore,it needs a new logistics information technology to replace the traditional mode of storage operation. RFID (radio frequency identification) and WSN (Wireless Sensor Network) technology can precisely solve this...
