The Routing Protocol for Low-power and Lossy Networks (RPL) is the standard IPv6 routing protocol designed by IETF, it is suitable for Low power and Lossy Networks (LLNs). However, the RPL network will suffer from network congestion, rapid consumption of key node energy and high packet loss rate in the case of heavy network load. In this paper, we propose a multipath routing optimization strategy for RPL, and carry out the simulation analysis of RPL and our proposal M-RPL with the COOJA Simulator. Simulation results show that our optimization strategy can handle well the situation of unstable links and network congestion, and reduce the average time delay of the network.
