Service requirements and capability framework for IoT-related crowdsourced systems can help the implementation of IoT-related crowdsourced systems. This Recommendation specifies service requirements of IoT-related crowdsourced systems, in addition to the requirements of IoT-related crowdsourced system [ITU-T Y.4205] and the common requirements of IoT [ITU-T Y.4100]. Based on these requirements, a capability framework of IoT-related crowdsourced systems is developed.
