Total lifecycle information sharing system of industrial products, particularly targetting\r\nconsumer electronics (CE), is presented. EPC (Electronic Product Code) of CE is stored in\r\nembedded dual interface RF tag and thus can be retrieved through both the RFID air\r\ninterface and the baseband interface. This way, consumers can discover and access\r\nservices associated with the CE by using EPC architecture even when the CE is connected\r\nto the network in consumer’s premise; i.e., home network. We develop a prototype of such\r\nextended EPC network. CEs are automatically recognized by the information system\r\nimmediately after they are associated to home network by using UPnP mechanism. In our\r\nimplementation, the home network is composed of Ethernet and ZigBee segment. UPnP\r\nextension using CoAP is developed to seamlessly establish end-to-end communications over\r\nthe ZigBee segment. The prototype involves about 50 appliances with 180 sensor data\r\nconnected with IPv6 network. We also evaluate and identify the performance bottleneck of\r\nthe prototype.
