Cloud architecture for tight interaction with the real world and deep sensor-data aggregation mechanism

The next-generation cloud computing systems are expected to be connected to the real world more tightly by massive amounts of sensors and actuators. Today´s clouds, however, are not capable of handling massive sensor data or giving fast feedback to the real world because of the long latency and limited bandwidth of WANs. We propose a cloud architecture that allows fast response to the real world in spite of floods of sensor data. We also present a deep sensor-data aggregation mechanism for the proposed cloud architecture to compress sensor data by an order of magnitude. Our evaluation results show that the deep sensor-data aggregation at the edges of clouds is effective in reducing network traffic sent over cloud networks.
