Efficient and scalable location and mobility management of EPCglobal RFID system

The addressing and networking are amongst the most important issues in order to make the Internet of Things (IoT) concept a reality. In the Radio Frequency IDentification (RFID) based IoT context, the most challenging issue is on the integration of the RFID network into the Internet Protocol (IP) network. The development of the RFID technology, which is driven mainly by the logistic related industries, is based on enterprise system that does not take full advantage of the IP based networking features, such as the mobility management. On the other hand, most of the existing works towards the integration of RFID and IP network do not take the full advantage of all the RFID middleware components defined in the EPCglobal standard. Therefore, the full integration of RFID middleware with the IP network through a testbed implementation which is fully compliance with the EPCglobal standard and having the location and mobility management at the same time, is the main contribution of this work. The performance of our proposed work is measured in terms of delay in two cases, i.e. tags registration and tracking, and thereafter it is compared with the existing RFID middleware implementation. The measurement results show that the delay of our proposed work is significantly lower than that of existing solution, especially in the tags registration case.
