Abstract
Wireless Sensors have seen a lot of applications in our daily lives in the recent years. The market has been flooded with high end consumer electronics using wireless sensor technology. However, most of the current technologies require the sensor to be in the vicinity of the end-user application. There has been some study in the techniques for sensor provisioning and sharing for the large number of existing Wireless Sensor Networks. Virtualization of Wireless Sensor Networks (WSNs) is a step forward in exposing these WSNs to large user base from remote locations. However, there is still a huge gap in bringing together information available from heterogeneous, distributed resources of Wireless Sensor Networks to a non-localized user. In this work, we utilize IaaS paradigm of Cloud Computing in virtualization of sensor networks which gives the flexibility of handling heterogeneous systems. The system also enables a smart device user to access information generated by Wireless Sensors through the cloud via SaaS based design. This allows the system to take common computational tasks to be hosted as a service through the cloud. It frees the smart device user from running heavy applications for data processing and storing. Thus, system provides the smart device user a Cloud Enabled Wireless Sensor Network infrastructure. The system architecture provides the necessary features for it to be scalable and flexible, ensuring reliable sensor data transfer and processing through cloud infrastructure. We also present a small test bed implementation of the system.
