Data Communication Parallel Multichannel Communications

Multichannel data communication system in which the stop-and-wait automatic-repeat request protocol for parallel channels with an in-sequence delivery guarantee is used for error control. Packet transmission over a single channel, in a multichannel communication system, multiple packets are sent at a time, one packet per channel, and packet transmission errors can occur across every channel.

To implement error control through retransmission of packets in a multichannel communication system. In a wireless communication system, however, the transmission condition of a wireless channel changes over time, and consequently, the channel is often severely affected by time-varying losses. In future work, we can apply the modeling and analytical approach presented in this paper to conducting performance studies on the selective-repeat ARQ protocol over parallel channels with time-varying channel models.
