Random Linear Network Coding (RLNC) is considered to be one of the promised
solutions to achieve the reliability of transmission in multi hop wireless networks, Since it
is based on correcting the loss of the packets in the medium through the conti
nuity of
transmitting coded packets from each segment until receiving acknowledgment of getting
the required number of these packets for decoding. However, because of the nature of
wireless medium and multi hops transfer, a loss or delay of the ACK may occur, which
causes transmitting extra packets and time delay to the next segments, consequently
decreasing the throughput of these networks.
In this research, we propose a new transmission mechanism for reliable transfer in
multi hops wireless networks through using the concepts of sliding window and fast
retransmit with RLNC, for transmitting packets of consequent segments in specific
continues flow and fast correcting the loss in these segments. Simulation results show that
proposed mechanism decreases the time delay for transmission process and increases the
transfer throughput of these networks.
