Abstract: In a wireless communication system configured to have a plurality of nodes, any one of the nodes receives a broadcast message from the nodes adjacent thereto, and calculates a reception time point variation that is difference between a time point when the message is received for each of the adjacent nodes and a time point when the preceding message is received. The reference time of the node is corrected based on the variation calculated for each of the adjacent nodes.

Abstract: PURPOSE: A resource allocating device for the interference evasion of a wireless communication system and a method thereof are provided to prevent receiving failure caused by interference generated by incomplete synchronization with neighbor nodes in a wireless mesh network. CONSTITUTION: An allocation control unit (230) selects a simultaneous receiving impossibility node and a simultaneous transmission impossibility node about each hop node of a node by using a signal quality value of each hop node. The allocation control unit excludes a transmission-expected resource of the simultaneous transmission impossibility node from a transmission resource during the transmission resource allocation of the node. The allocation control unit excludes the transmission-expected resource of the simultaneous transmission impossibility node from a receiving resource of the node during the receiving resource allocation of the node.
