7. An ad-hoc network system comprising:
relay nodes configured to verify state information representing a relative distance and angle to a neighboring node capable of receiving data when the data is transmitted,
wherein the relay nodes are configured to:
determine, based on the state information, an action representing a change over time of each relay node;
determine, based on an amount of energy consumption according to the action and an amount of change in a network throughput determined according to the state information changed according to the action, a reward corresponding to the action;
change a transmission range of each of the relay nodes according to a transmission range radius at a previous time and a transmission range radius at a current time;
determine whether the changed transmission range is greater than a changeable range;
determine the reward when the changed transmission range is less than or equal to the changeable range; and
re-determine the action when the changed transmission range is greater than the changeable range; and
build a network including a source node, a destination node, and a plurality of relay nodes by generating, based on the reward, a policy that allows a cumulative reward to be maximized.
