Abstract
The IPv6 routing protocol for low-power and lossy networks (RPL) is a routing protocol widely used for internet of things (IoT). However, there is no RPL-based routing protocol designed for real-time effective routing in a fire incident scenario. The characteristics of sensor networks in a fire incident are that sensors or IoT devices are continuously broken, which varies the graph in RPL continuously. Therefore, this study proposes an emergency RPL (EMRPL), which can predict the trajectory of fire effectively and transmit sensing data during a fire incident in real-time. Compared with RPL, EMRPL can effectively increase the packet delivery ratio. This shows that EMRPL has higher efficiency and can be effectively applied to fire incidents.
