Enabling Sensor as Virtual Services through Lightweight Sensor Description

This paper proposes a virtualized Internet of Services (IoS) space framework for connected objects. The framework allows to expose the connected objects sensor capabilities, functionalities and data as virtual sensor services and advertise these services to social network sites in addition to service registries for the enablement of a connected people IoS space. In this regard, we develop lightweight ontologies both for sensor capabilities and functionalities and the IoS space. The paper also offers a policy based service execution approach to abate the traffic to and from a sensor node which in turns increases the sensor node battery life. We select an electrical vehicle as case study and implement a proof-of-concept by using semantic technologies and Sun SPOT sensor platform.
