The invention discloses a self-organizing low-power-consumption wireless network IP address administration method. The method comprises the steps of S1, carrying out hierarchical division on the equipment in a system and dividing the equipment in a self-organizing low-power-consumption wireless network into three hierarchies, S2, distributing an IP address to the equipment of each hierarchy and distributing IP addresses to all the equipment in the network to enable each piece of equipment to be provided with only one IP address, and S3, building a mapping relation between the IP addresses and the physical address MAC of a wireless module. According to the self-organizing low-power-consumption wireless network IP address administration method, the hierarchical division of the equipment in the wireless network is achieved, binding of IP addresses and network equipment MAC is achieved, the physical route of data transmission is determined according to source IP addresses and target IP addresses, and therefore transmission of data in specified physical equipment is achieved. The self-organizing low-power-consumption wireless network IP address administration method has the advantages of being capable of avoiding mis-awakening and reducing address detecting time for the equipment, and finding the physical route of point-to-point communication accurately.
