A New Method of IPv6 Addressing Based on RFID in Small Objects Networks

SmObnet6 (Small Objects Network based IPv6) is a generic term which is used to define either small or large networks that could be interconnected with small objects in IoT context. RFID is one of the famous technologies used in internet of thing. Despite their low costs and high quality, how RFID tags could make small objects communication via internet knowing that they have just a hexadecimal identifier and they do not have an IP address? To answer this question, several solutions are proposed in the literature. In this paper, we propose an algorithm based on the logical operator AND inclusive between the network prefix and the tag ID to derive an IPv6 address of the tag from its ID. In this way, RFID-IPv6 mapping provides better solution for objects because it minimizes the chances of address conflicts in the network.
