Abstract: Techniques are disclosed for adaptive coding and scheduling of packets in wireless networks. The adaptive coding and scheduling can be achieved by utilizing a discrete water filling (DWF) scheme. In an example, a computer-implemented method to adaptively code and schedule packets in a wireless network may include determining number of paths between a sender and a receiver in a multipath (MP) network, determining erasure rates for each path of the paths between the sender and the receiver, and determining a multipath rate. The method may also include determining a coding bucket size based on the multipath rate and determining a multipath delay for the coding bucket size and the erasure rates. In another example, the adaptive coding and scheduling techniques can be applied to a multihop multipath (MM) network.

Abstract: Techniques are disclosed for an adaptive and causal random linear network coding (AC-RLNC) with forward error correction (FEC) for a communication channel with delayed feedback. An example methodology implementing the techniques includes transmitting one or more coded packets in a communication channel, determining a channel behavior of the channel, and adaptively adjusting a transmission of a subsequent coded packet in the first channel based on the determined channel behavior. The communication channel may be a point-to-point communication channel between a sender and a receiver. The channel behavior may be determined based on feedback acknowledgements provided by the receiver. The subsequent coded packet may be a random linear combination of one or more information packets.
