Data dissemination in wireless broadcast channels: Network coding versus cooperation
2009
IEEE Transactions on Wireless Communications
Preserved Fulltext
Network coding and cooperative diversity have each extensively been explored in the literature as a means to substantially improve the performance of wireless networks. ...
We show that if K is fixed, cooperation outperforms network coding, in the sense that the expected delay is proportional to K (and thus within a constant factor of the optimal delay) in the former case ...
In wireless networks, network coding has been proposed for disseminating information to all receivers [3] and has been shown to provide excellent delay performance compared to round-robin scheduling, ...
