To support verifiable Boolean range queries, we propose an accumulator-based authenticated data structure that enables dynamic aggregation over arbitrary query attributes. Two new indexes are further developed to aggregate intra-block and inter-block data records for efficient query verification.
In this paper, we argue that peer-to-peer (P2P) overlays are well suited for IoT systems. However, existing P2P systems do not efficiently handle queries of data within a range, which is a popular ...

This paper presents RobP2P, a robust architecture to construct mobile P2P networks and efficiently maintain the network state. RobP2P introduces a novel super-peer selection protocol based on an aggregate utility function that takes into account peers' capability and context.

We investigate the problem of processing historical queries on a sensor network. Since data is considered to have been already collected at the sensor nodes, the main issue is exploring the spatial component of the query in order to minimize its cost represented by the energy consumption.

The main challenge in P2P approximate query processing is to select the optimal subset of peers to which the query is forwarded. However, the selection criteria for this subset are completely different for top-k and aggregate queries.While in top-k the goal is to identify the peers holding top objects, approximate aggregate querying algorithms …
In corporate networks, daily business data are generated in gigabytes or even terabytes. It is costly to process aggregate queries in those systems. In this paper, we propose PACA, a probably approximately correct aggregate query processing scheme, for ...
