Abstract: PURPOSE: A system and a method for the integral operation of an unmanned robot are provided to perform an adaptive and effective task by performing collaboration through integration control based on sharing tasks and hierarchical authorization. CONSTITUTION: An RMS(Remote Mission Station)(110) provides the operational aurthorization of an unmanned robot per ROS by allocating unmanned robots(310,320) and tasks to perform per ROS(Remote Operation Station)s(210,220). The ROS selectively operates the allocated unmanned robots and controls the operation about the allocated unmanned robots. A wireless transceiving unit performs as a remote task device, the ROS, and communication between the unmanned robots. The remote task device classifies a function which is controllable to an unshared and shared task. The shared task gives temporary control rights to other ROSs which have not received the operational authorization.

Abstract: PURPOSE: A virtual transmission apparatus for a dynamic topology characteristic in ad-hoc network is provided to prevent the deterioration of transmission success rate due to a topology secession. CONSTITUTION: It is determined whether a request for data transmission or retransmission is generated or not(S300). A terminal inspects a communication topology. It is determined whether a destination address exists within the communication topology or not(S310). If the destination address does not exist within the communication topology, a virtual transmission is performed instead of a real data transmission(S320).
