PURPOSE: A network system and routing method thereof are provided to determine a minimum cost path by calculating link costs based on a weighted value element including the residual energy state of nodes. CONSTITUTION: When available resources for inputted flows are existed, a network system calculates a path gain between a reception node and a predetermined transmission node and link costs based on weighted value elements including a residual energy state of nodes(S1310,S1320). When the available resources are not existed, the network system rejects the inputted flows(S1340). The network system determines a minimum cost path based on the calculated link costs(S1330).
