Accurate Data Aggregation on Unstable Structured P2P Network

Smartphones and sensor devices have come into widespread use, and we can observe huge amounts of data from the devices via the Internet. In order to develop a network application which uses these devices effectively, we need an accurate and scalable data aggregation mechanism. In this paper, we propose a accurate data aggregation mechanism which is based on a scalable structured p2p network. The proposed mechanism is constructed by two concepts: Asynchronous Data Aggregation and Time-slot-based Data Aggregation. In the proposed mechanism, the amount of communication data required for data aggregation is O (log N), where N is the number of nodes. Additionally, the proposed mechanism achieves accurate data aggregation even if the structured p2p network is unstable. In this paper, we explain an algorithm and a communication protocol for the proposed data aggregation mechanism. Furthermore, using experimentally obtained results, we indicate advantages of our proposal over existing data aggregation mechanisms.
