Abstract:
This paper proposes a deepwater monitoring system built with sensors distributed in Campos Basin offshore area. The underwater communications are undertaken by underwater acoustic modems installed on the sensors and vessels used for logistic support of the oil exploration. However, the vessels may not be within sensor range at all times, requiring the use of DTN (Delay/Disruption Tolerant Network). This work investigates the Monitoring system feasibility, analyzing the network behavior using ONE (Opportunistic Network Environment) simulator, adjusting the simulation scenarios to the characteristics of the Brazilian oil exploration area.
