摘要：This paper first describes the dynamic multicast routing and routing optimization standard, then puts forward the RPL protocol based energy efficient DODAG multicast routing algorithm. Through simulation experiments, we can compare and analyze the advantages and disadvantages of several kinds of dynamic multicast routing algorithm. And according to the simulation results obtained conclusion, EE - DODAG multicast in the process of each packet sent after more a small amount of forwarding nodes, and consume less energy in survival time.
