Database Solution for Sensor Data with Authorized Data Access Solution

Due to the growth of the Internet and the device diversity together with their communication capability the Internet of Things (IoT) is a hot topic. The Internet of Things is not limited to Peer-to-Peer (P2P) networks and devices like server, computers, and routers any more. It also includes wireless sensor devices connected in a Wireless Sensor Network (WSN).

The application range goes from intelligent homes, logistic, health care to environmental monitoring. All applications have in common a high amount of collected sensor data (e.g., temperature, brightness, humidity). To make the collected data accessible for further processing and analysis two requirements must be fulfilled: (1) Storing the data in an efficient manner and (2) allow access only for authorized users.

The task of this assignment includes answering the following questions:

• What strategies for storage solutions for sensor data exist (e.g., TinyDB)?
• What requirements does an efficient storage solution need to fulfill?
• How can data access for authorized users be guaranteed?

Based on the received answers of those questions an efficient and secure data storage solution needs to be design and developed, which is finally integrated in the existing solutions within SecureWSN, especially for supporting offline visualization and therefore accessing „old“ data.
