Antarctica is a key location for many research fields. The lack of telecommunication systemsthat interconnect remote base camps hardens the possibility of building synergies among differentpolar research studies. This paper defines a network architecture to deploy a group of interconnectedremote Antarctic wireless sensor networks providing an IoT telemetry service. Long backhaul NVISlinks were used to interconnect remote networks. This architecture presents some properties fromchallenging networks that require evaluating the viability of the solution. A heterogeneous layer-based model to measure and improve the trustworthiness of the service was defined and presented.The model was validated and the trustworthiness of the system was measured using the RiverbedModel simulator.
