PURPOSE: An apparatus for providing optimum routing protocol in a multi hop decode-and-forward relay and a method thereof are provided to perform optimum resource allocation by considering more realistic communication environment, by considering a network model suitable for a real communication system where nodes making an interference signal are randomly distributed. CONSTITUTION: A hop count setting unit (610) sets hop count which is to be used in signal transmission between a source and a destination. A parameter determining unit (620) determines a system parameter minimizing outage probability, on the basis of the set hop count. The parameter determining unit determines distance between hops equally. The parameter determining unit determines transmission power so that transmission power of each hop is equal. The parameter determining unit determines time fraction so that time fraction allocated to each hop is equal.
