Present broadcast approaches for wireless multi-hop networks distribute packets quickly to all nodes (i.e., with low latency) by constructing small broadcast trees, thereby reducing the number of forwarding transmissions. While these trees are sufficient in non-fading environments, the authors show that they have a low delivery rate under fading. As a solution, they incorporate the Rayleigh fading model directly into tree construction to re-obtain complete distribution with high probability. To still achieve low latency at the same time, they combine transmissions at individual nodes to exploit cooperation diversity.
