Abstract: PURPOSE: A multicast data transmission system utilizing location information in a wireless ad-hoc network and data transmission method thereof are provided to prevent the creation of overlapped data and to promote network performance by effectively utilizing wireless resources. CONSTITUTION: A source node acquire information of neighbor nodes(S10). The source node selects one or more intermediate nodes locates one hop distance with the source node(S20). The source node selects the intermediate node which locates to the direction of a destination node as one or more relay nodes for transmitting data(S30). The intermediate node is selected based on the location information of the destination node and the location information of the intermediate node. The intermediate node transmits the data received from the source node to the destination node(S40). [Reference numerals] (AA) Start; (BB) End; (S10) A source node acquire information of neighbor nodes; (S20) A source node selects intermediate nodes; (S30) A source node selects the intermediate node and transmits data to a relay node by considering directivity; (S40) Each relay node transmits data to the destination node by transmitting the data to the relay node of a next hop

Abstract: PURPOSE: A frequency allocating method and wireless connection method in a femtocell within a mobile communication network including LTE(Long Term Evolution) are provided to increase the performance of a macro cell user through handover from macrocell to femtocell eNB(envolved Node B). CONSTITUTION: A plurality of femtocell base station areas(210,220) is included within a marcocell eNB area(200). The macro cell base station area is divided into two or more small areas. The frequency is allocated to the macrocell in a small range to the femtocell.

Abstract translation: 目的：提供包括LTE（Long Term Evolution，长期演进）在内的移动通信网络中的毫微微小区中的频率分配方法和无线连接方法，以通过从宏小区到毫微微小区eNB（包括节点B）的切换来提高宏小区用户的性能。 构成：在蜂窝基站eNB区域（200）内包括多个毫微微小区基站区域（210,220）。 宏小区基站区域分为两个或更多个小区域。 频率被分配给在小毫微微蜂窝小区的宏小区。
