US 2013/0272201 A1 · WIRELESS COMMUNICATION METHOD AND APPARATUS THEREOF

Abstract

To provide a stable high speed wireless network, the relay process is solved at the lower layers (PHY layer, MAC layer) without depending on upper layers to reduce the load of the upper layers to the utmost. Discrimination is made between a packet of one's own station and a relay packet to process the presence and absence of the relay packet without using a CPU to construct a wireless network executing the relay processing at a high speed. Further, the retransmission is executed without using a CPU to provide a stable wireless network. In addition, the table for relay process (routing table) is constantly updated to add to the table the information of the packets of which processes are not executed to eventually suppress unnecessary processes.

Claims11

Dependent claims

A wireless communication method for performing transmission and reception while relaying a packet within wirelessly transmitted data, the method comprising the steps of:

identifying a header of the received packet;
determining a destination of the received data based on the recognized header;
recognizing a next transmission destination by looking up a table, if the determined destination is not one's own station;
determining a packet to be relayed based on the recognition of said header and the recognition of said transmission destination;
selecting from said packets determined to be relayed, a packet to be transmitted among packets to be transmitted between packets to be transmitted by an application of one's own station;
and
transmitting the selected packet.

4 more elements

A wireless communication apparatus for performing transmission and reception while relaying a packet within wirelessly transmitted data, the apparatus comprising:

reception unit for receiving wirelessly transmitted data;
header recognition section for recognizing a header included in the data received by the reception unit;
one's own-station packet determining section for determining whether the data received by the reception unit is directed to one's own station;
table for recognizing a next transmission destination based on the destination of the data received by the reception unit;
relay station packet determining section for determining a packet to be relayed through the table and the header recognition section;
storage unit for temporarily storing the transmission packet from an application of one's own station;
transmission packet selection unit for selecting either the packet stored in the storage unit or the packet determined by the relay station packet determining section;
and
transmission unit for wirelessly transmitting the packet selected by the transmission packet selecting section.
