Wireless sensor networks for logistics and retail

• Internet of Things technologies makes it possible to trace when and where the excellent food or wine is spoiled or loses perfect taste in logistics and retail. This paper describes a system using a two-layered wireless sensor network to monitor the supply chain from manufacturer to consumer, including the network topology, application software on server, and sensor node hardware. It employs GSM/GPRS as the high layer network and semi impulse ultra-wideband radio (IR-UWB) for the low layer communication. We propose GSM Cell-ID location technology for tracking the goods transportation, and time-of-arrival method for local positioning. Finally, the first version of the system implementation and future work are presented. ©2009 IEEE.
