This paper proposes a Sensing Service Framework for integrating Wireless Sensor Networks (WSN) and cloud infrastructure to impart climate alerts and perform climate analysis at reduced cost. This paper also provides a literature survey of related works on Sensor and Network level Virtualization. Factors that determine climate are humidity, temperature, wind speed, sun movement and so on. Drawbacks of prior work are sensor and network level virtualization not employed. The proposed work overcomes by deployment of WSNs components for many climate applications by employing virtual sensor and climate overlay approach. Sensing service framework monitors climate data by issuing Sensing Service and social media alerts. All these factors improve and provide climate updates to customers and climate analysts at reduced price.
