The IETF suggests a IoT(Internet of Things) routing protocol which is named RPL(IPv6 Routing Over Low power and Lossy networks) that could accept requirements of a lot of routing issues in IoT environment and discussion is progressing on the routing metric or route determination. The RPL is optimized to collect environment information in static network, but it is not possible to stably maintain the routing path in the service environment that has many devices which move frequently in RPL network. In this paper, we propose a FPD (Fast Path Discovery) algorithm for a seamless service of mobile nodes in the IoT environment requiring mobility. The FPD-based mobile node provides a seamless service by dynamically determining the DIS message transmission period to select a parent node.
