WIRELESS DEVICE

摘要

A wireless device that can realize a low delay while ensuring reliability when FEC is applied to multicast communication via a wireless LAN. The wireless device includes a correction-coding consecutive-transmission determination unit that determines as to which of correction-coding and consecutive-transmission of information packets should be transmitted based on communication state with a packet destination terminal, a packet identification accumulation unit that identifies and accumulates information packets acquired from the correction-coding consecutive-transmission determination unit, a correction-coding control unit that performs correction coding and correction decoding of information packets acquired from the packet identification accumulation unit, and a consecutive-transmission control unit that duplicates and complements the information packets acquired from the packet identification accumulation unit .

主权项

1. A wireless device comprising: a correction-coding consecutive-transmission determinator that determines as to which of correction-coding and consecutive-transmission of information packets should be transmitted, based on information of a communication state with a packet destination terminal;
a packet identification accumulator that identifies and accumulates information packets acquired from the correction-coding consecutive-transmission determinator; a correction-coding controller that performs correction coding and correction decoding of information packets acquired from the identification accumulator; and consecutive-transmission controller that duplicates and complements the information packets acquired from the packet identification accumulator, wherein the correction-coding consecutive-transmission determinator performs determination based on either information of throughput between the packet destination terminal and the wireless device itself, or information of a number of information packets accumulated in the packet identification accumulator.
