Abstract: PURPOSE: A resource allocation method in a wireless network is provided to adaptively allocate resources according to the conversion of topology in each node. CONSTITUTION: When a node is added to existed topology, the node receives a beacon message from a neighbor node(S800,S810). The node competes with the neighbor nodes for reserving a beacon slot(S820). When a collision is generated, the node notifies the collision during a beacon transmission section(S830,S840). When the collision is not generated, the node selects the beacon slot(S850). The node notifies the selected beacon slot to one hop neighbor node(S860).

Abstract: PURPOSE: A topology control method in a wireless network is provided to simultaneously reduce the energy consumption and interference of a node by determining optimal transmission power by determining the optimal number of neighbor nodes. CONSTITUTION: Interference for interference nodes is calculated using present transmission power(S1050). A candidate neighbor node is selected from a candidate neighbor node group according to a distance(S1060). Candidate transmission power satisfied with a target SINR(Signal-to-Interference plus Noise Ratio) of the candidate neighbor node is allocated to the node(S1070). Interference generated by the candidate transmission power for an interference node is calculated(S1080). When a formula(Iic >= Ii) is satisfied, the node is included in the candidate neighbor node group(S1090,S1100).
