Criteria | Underwater Sensor Networks | Floating Sensor Networks |
Cost | -Complex node design -Advanced hardware protection | Less complexity required in transceiver design and node processing |
Deployment/ Maintenance | -Heavy and bulky due to hardware protection -Difficult to maintain once deployed | Relatively easy both to deploy and retrieve for maintenance purposes. |
Medium | No optimal communication medium | -No underwater communication necessary -ZigBee, 6LoWPAN can be used |
Power Supply | -Complex DSP resulting in higher power requirements -Difficult to replenish power | -Reduced communication power requirements -Easier to replace/recharge power supply |
Localization | No firmly established method. | Can be used with GPS to accurately establish the node’s position. |
Security | Increased power requirements, less power available for security protocols. | Can take advantage of establish standards that consider security, such as ZigBee/6LoWPAN |
