With therapid development of wireless communication technology, the threemeter (water, electric, gas) centralized meter readingbased on intelligent community networking technology is further mature.The current protocol does not consider the requirement of centralized meter reading whichneed lowerfrequency and power consumption. Based on AODV（Ad Hoc ondemand distance vector）routing protocol, a method named DEAODVwhich is based on the distance between nodes and the energy of node is proposed in this article. By combining the two factors, the transmission path of the message is reasonable selected as well as save the packet cost and improve the link lifetime.The theoretical analysis and experimental simulation show that the proposed DEAODV algorithm can effectively save the message overhead and improve the link life cycle in the application of threemeter centralized meter reading.
