Provided is a wireless communication system easily establishing a connection path in a sensor network collecting data from a number of sensor nodes. The wireless communication system comprises a base station communicating by a first wireless communication system, plural first nodes communicating by the first wireless communication system and a second wireless communication system, and plural second nodes communicating by the second wireless communication system. The first node transmits the number of hops in the first wireless communication system to the second node. The second node obtains a reception condition of at least one of a signal transmitted by the first node and a signal transmitted by the second node, and selects a upper stage node to connect based on the number of hops in the first wireless communication system, the number of hops in the second wireless communication system, and the obtained reception condition information.
