Sensing as a Service - Architectures for Closed-loop Sensor Network Virtualization

Abstract:

The goal of this project is to demonstrate that new cyber physical architectures will enable closed--loop sensor networks to be shared among multiple applications and to dynamically allocate sensing and computing resources necessary to analyze sensor data and perform sensor actuation. The sharing of sensor network infrastructures will make the provision of data (e.g., weather information) more cost efficient and will create cyber infrastructures, which will result in a dramatic increase in the number of sensor networks available for use. The proposed architectures will introduce a new paradigm, which we call Sensing as a Service, in which users can obtain sensing and computational resources to generate the required data for their sensing applications. In this poster, we give a motivation for this approach, introduce the overall system architecture, and demonstrate the benefits of the computation virtualization layer SaaS. In addition, we present initial results of a simple sensor/actuator virtualization approach based on data obtained from an actual sensor network.
