Abstract: PURPOSE: A stable communication providing method in ubiquitous environment and apparatus thereof are provided to effectively avoid frequency interference generated by using a specific frequency band in adjacent environment through a ubiquitous health service communication by using plural transmission and reception apparatuses. CONSTITUTION: A channel state monitoring unit(120) monitors channel states of a first transmission and reception apparatus. A data transmission rate checking unit(130) checks transmission rates of data transmitted by the first transmission and reception apparatus. A selecting control unit(110) of a transmission and reception apparatus selects a second transmission and reception apparatus based on the checked data transmission rates. The selecting control unit of the transmission and reception apparatus transmits a response request packet to an external apparatus. When the reception signal strength of a response packet is under threshold values, the selecting control unit of the transmission and reception apparatus selects the second transmission and reception apparatus.

Abstract: PURPOSE: An address allocation method and a routing method in low power consumption wireless communication network are provided to increase effectiveness of the address allocation by making use of the unused address possible. CONSTITUTION: An address is allocated according to DAAM(S100). In case the additional address allocation is impossible according to DAAM, if the additional address allocation request is inputted from a new node, the additional address is allocated according to RAAM(S130). The node to which the addition address is allocated receives the address allocation request from the other new node(S140). According to the additional address request, the other new node is allocated by RAAM.
