Sensing services in cloud-centric Internet of Things: A survey, taxonomy and challenges
Burak Kantarcı, Hussein Talaat Mouftah · 2015
Virtually interconnected objects with unique identifiers and computing, communication and sensing functionalities form the Internet of Things (IoT) architecture. In the cloud-centric IoT concept, IoT objects can provide sensing services based on a cloud-inspired business model. Smart mobile devices have a great potential to improve the performance of IoT applications by enabling access to their built-in sensor data through cloud servers based on the pay-as-you-go fashion. Such an architecture requires effective sensing service provider search techniques accompanied with effective recruitment algorithms for sensing service providers. Moreover, reliability and trustworthiness of sensing service provisioning is a crucial challenge. This paper provides a brief survey of the state of the art in sensing services over cloud-centric IoT, and presents recent research that addresses the challenges that are mentioned above. Moreover, the paper aims at defining a taxonomy of the surveyed schemes while reporting open issues, existing challenges and possible research directions.
