Summray of proposals with main focus on improving transmission efficiency via multi-hop pipelining.
| Protocols | Fineness | Recovery Mechanism | Pipeline Spacing | Transmission Sequence | Strucure |
|---|---|---|---|---|---|
| Deluge [39] | Page level | NACK | 3 hops | In-sequence | None |
| Modeling [46] | Page level (with optimal page size) |
NACK | 3 hops | In-sequence | None |
| Sprinkler [41] | Packet level | Piggybacked ACK | 3 hops | In-sequence | CDS |
| GARUDA [45] | Packet level | Piggybacked ACK | 3 hops | Out-of-sequence | CDS |
| Typhoon [36] | Page level | NACK | 2 hops | In sequence | None |
| Splash [47] | Packet level | NACK (in recovery phase) |
2 hops | Out-of-sequence | Tree |
