Utility Optimal Coding for Packet Transmission
over Wireless Networks – Part II:
Networks of Packet Erasure Channels.
We define a class of multi–hop erasure networks that
approximates a wireless multi–hop network. The network carries
unicast flows for multiple users, and each information packet
within a flow is required to be decoded at the flow destination
within a specified delay deadline. The allocation of coding rates
amongst flows/users is constrained by network capacity. We
propose a proportional fair transmission scheme that maximises
the sum utility of flow throughputs. This is achieved by jointly
optimising the packet coding rates and the allocation of bits of
coded packets across transmission slots.
