Method for selecting wireless communication path

A method of selecting a wireless communication path in a wireless network which includes a first wireless communication apparatus, a second wireless communication apparatus, and a relay apparatus, and allows direct communication between the first wireless communication apparatus and the second wireless communication apparatus,

• wherein at least a communication scheme between the first wireless communication apparatus and the relay apparatus is identical to a communication scheme between the second wireless communication apparatus and the relay apparatus, said method of selecting a wireless communication path comprising the following performed by the first wireless communication apparatus:
• storing a threshold group including one or more values;
• determining one of the one or more values in the threshold group as a threshold based on a capability of the relay apparatus;
• comparing the threshold with a received signal strength indicator of a packet sent by direct communication from the second wireless communication apparatus to the first wireless communication apparatus;
• and
• determining a communication path for a packet to be sent to the second wireless communication apparatus.
