Existing routing protocols are focused on the common Mes h routing in wireless sensor network.In the energy efficiency information netwo rk

the data acquisition measurement node and the volume and the node position of energy efficiency information are almost fixed

which lead to low efficiency of traditional wireless sensor network routing applications in energy efficiency information network.According to the above characteristics of the energy effic iency information network

a novel routing method based on energy efficiency ser vice was proposed by integrating SPIN routing protocol and the basic idea of dir ected diffusion routing mechanism.High efficient communication channel was esta blished between energy efficiency terminals and concentrator.The updating and c onfiguration process and optimization analysis of the best route length of SPIN-DD was described by the 4-node simulation topology.Finally

the simulation p latform of energy efficiency information collection network was constructed in O Mnet to verify the proposed method

and simulation results show that

compared w ith the existing methods

SPIN-DD reduces unnecessary neighbor relationship mai ntenance in routing propagation and routing updates and has shorter transmission delay as well as less network overhead.
