Sensors on (or attached to) mobile phones can enable attractive sensing applications in different domains such as environmental monitoring, social networking, healthcare, etc. The authors introduce a new concept, Sensing-as-a-Service (S2aaS), i.e., providing sensing services using mobile phones via a cloud computing system. An S2aaS cloud should meet the following requirements: it must be able to support various mobile phone sensing applications on different Smartphone platforms. It must be energy-efficient. It must have effective incentive mechanisms that can be used to attract mobile users to participate in sensing activities.
