A structured overlay network for aggregating sensor data

Symbiotic computing services require big data from a huge number of sensor devices in order to detect the real-world, so a distributed database system which can handle the big data is required for symbiotic computing system. In this paper, we propose a scalable structured p2p network which supports data aggregation. In the proposed p2p network, each node forwards partial statistical results to other nodes, and each node aggregates partial statistical results in order to calculate a complete statistical result. In the proposed p2p network, the data aggregation process does not need any specific protocols, so the communication cost of the extension mechanism is very low. We simulated the proposed p2p network by using a p2p network simulator. The simulation results indicate that the proposed data aggregation mechanism is effective enough.
