摘要： 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).
