A Summary of the reliability issues for different sensor network architectures for underwater pipelines.
| # | Architecture | BW | BWF | EC | PSC |
|---|---|---|---|---|---|
| 1 | Underwater wired sensor network | High | 0 | No | High |
| 2 | Underwater acoustic wireless sensor network | Low | Low | Yes | Low |
| 3 | RF Wireless sensor network | Med | Med | Yes | High |
| 4 | Integrated wired/acoustic wireless sensor network | High | Low | No | Low |
| 5 | Integrated wired/RF wireless sensor network | High | Med | No | Low |
BW: Bandwidth; BWF: Bandwidth with fault condition; EC: Energy constrains; PSC: Physical security concern.
