Patent ID: 8179880

Claim:
A wireless communication method for transmitting and receiving information in a predetermined period by a plurality of wireless nodes capable of performing wireless communications, comprising: transmitting a time synchronizing signal for synchronizing the time among the plurality of wireless nodes to the plurality of wireless nodes by multihop, wherein optional information from a predetermined wireless node to an optional wireless node is transferred by the multihop through the same path as a transfer path of said time synchronizing signal by the plurality of wireless nodes, and information about the optional information from the optional wireless node to the predetermined wireless node is transferred by said multihop through a path inverse to the transfer path of said time synchronizing signal by the plurality of wireless nodes, and wherein a speed at which information is communicated between said wireless nodes along the path inverse to the transfer path of said time synchronizing signal is adjusted to be higher than a speed at which information is communicated between said wireless nodes along the transfer path of said time synchronizing signal.
