Research on Improvement and Optimization Design of Mobile Switching in RPL Routing Protocol

Abstract

In response to the shortcomings of the current RPL routing protocol, fully utilizing the idea of opportunistic routing, this study proposes an improved RPL routing protocol node mobility switching method to enhance the mobility support of wireless sensor IPv6 networks. Analyze existing RPL routing protocol solutions and identify their shortcomings; Analyze the challenges encountered in designing and improving routing protocols, and based on the specific application of RPL in 6LoWPAN technology, propose an overall design concept for the mobile switching method of an improved RPL routing protocol; Then, specific design will be carried out for the improved routing protocol mobile switching method, including mobile node detection, discovery and selection of the optimal parent node, link switching, etc; Finally, simulation implementation is carried out to verify its low energy consumption and low latency. Its research content involves disciplines such as the Internet of Things, computer simulation technology, and computer network technology, and has high theoretical and practical value.
