Network Coding-Aware Rate Control and Scheduling in Wireless Networks

Free registration required

Executive Summary

Network coding has been recently applied to wireless networks to increase throughput. It is typically implemented as a thin layer between MAC and IP, transparently to higher layers. In this paper, the authors study rate control and scheduling over wireless networks with intersession network coding, as a utility maximization problem. They describe that there is benefit from making rate control and scheduling aware of the underlying network coding. The key intuition is that network coding introduces new network coded flows and eventually new conflicts between nodes, which should be taken into account both in rate control and in scheduling.
