Medium Access Control for Opportunistic Routing – Candidate Coordination
Kai Zeng, Wenjing Lou, Ming Li · 2011
This chapter analyzes the coordination problem in opportunistic routing. It describes five state-of-the-art candidate coordination schemes, and based on this a new coordination scheme: “fast slotted acknowledgment” (FSA), which fully takes advantage of the channel detection approach to coordinate the packet forwarding among multiple candidates. The author compares FSA with those state-of-the-art schemes and simulation results show that it achieves better performance in all the metrics, especially in time delay. The simulation also validated that FSA can achieve similar performance to ideal coordination where relay priority can be ensured and duplicate packet forwarding is avoided.
