Determination apparatus and method path for data transmission in mobile communication system which consist of nodes

The invention in a mobile communication system composed of at least one adjacent node and the base node and the source node to the base node is transmitted to relay the requested adjacent data node or transmitted directly, the request with the path where the source node is determined in in transmitting the data, for data transmission between each node measures the required power, determining a path in sequence with the use of the measured power power required for data transmission from the base node to the source node consumes the minimum and it transmits the requested data using the determined path. Ad-hoc, sensor network, power consumption, multi-hop
