In the context of IoT communication models, the cloud-to-cloud model facilitates authorized third parties' access to data generated by IoT devices. In this model, different cloud service providers or platforms communicate with each other, allowing for the sharing and accessing of data stored in their respective clouds.

This structure is particularly useful for integrating different IoT systems and enabling collaboration between various applications and services. For instance, if one cloud platform collects data from various IoT devices and another cloud stores analytical tools or applications, the cloud-to-cloud model enables them to work in tandem. Authorized third parties can gain access to relevant data from these linked cloud services, enhancing interoperability and data utilization.

In contrast, other IoT communication models, such as device-to-device or device-to-cloud, focus more on direct communication paths either between devices or from devices to a central cloud, with limited capability for external third-party access. The gateway-to-gateway model is more concerned with communication between gateways rather than direct access for third-party users. Thus, the cloud-to-cloud model stands out as the most appropriate choice for authorized third-party access to IoT data.
