Opportunistic network coded information exchange among multi-user
Shitang Li, Baoyu Zheng · 2008
This paper investigates the strategies of relaying based on opportunistic network coding over wireless communication context with two pairs of users and one common relay exchanging their data, where the relay node can transmit either network-coded or un-coded packets. Resorting to a Markov model, the paper characterizes the average packet delay and energy power consumed by the relay node. The results of simulation indicate that there exists some tradeoff between delay and energy power.
