Abstract: PURPOSE: A resource allocation method in a wireless communication system is provided to reduce interference between users by allocating a slot having the highest performance index among unoccupied slots in an OFDMA(Orthogonal Frequency Division Multiple Access) type ad-hoc system to a terminal. CONSTITUTION: A resource allocating device senses a subcarrier already being used by the other terminal among all of subcarriers(S410). The resource allocating device obtains a time error, a frequency error, and receiving power information of the occupied subcarrier(S420). The resource allocating device calculates an SINR(Signal-to-Interference plus Noise Ratio) of unoccupied subcarriers(S430). The resource allocating device allocates a subcarrier having the highest SINR among the unoccupied subcarriers to a terminal(S440).

Abstract: PURPOSE: A routing method for supporting QoS(Quality of Service) in a wireless network and apparatus thereof are provided to allocate resources by establishing a connection for each intermediate node in the wireless network. CONSTITUTION: A connection management unit determines a next node and a predicted path in order to contact to a destination node(S600). The connection management unit deducts the QoS of a link(S610). The connection management unit requests resource allocation to a resource allocation unit in order to satisfy with the QoS of the link(S620). When the allocated resource is satisfied with the QoS of the link, the connection management unit transmits a connection establishment request to the connection management unit of the next node(S630,S640). The connection management unit stores connection information(S650).
