  • Aggregate query processing in the presence of duplicates

    Aggregate query processing in the presence of duplicates

    Mar 10 2015 · Wireless sensor networks WSNs have received increasing attention in the past decade In existing studies for query processing of WSNs each sensor node measures environmental parameters such as temperature light and humidity around its location

  • An adaptive innetwork aggregation operator for query

    An adaptive innetwork aggregation operator for query

    In this paper we propose an adaptive innetwork aggregation operator for query processing in sensor nodes of a WSN called ADAGA ADaptive AGgregation Algorithm for sensor networks The ADAGA adapts its behavior according to memory and energy usage by dynamically adjusting datacollection and datasending time intervals

  • Query Privacy Preserving for Data Aggregation in Wireless

    Query Privacy Preserving for Data Aggregation in Wireless

    Wireless Sensor Networks WSNs are increasingly involved in many applications However communication overhead and energy efficiency of sensor nodes are the major concerns in WSNs In addition the broadcast communication mode of WSNs makes the network vulnerable to privacy disclosure when the sensor nodes are subject to malicious behaviours

  • PrivacyPreserving and Dynamic Spatial Range Aggregation

    PrivacyPreserving and Dynamic Spatial Range Aggregation

    Apr 22 2019 · Abstract The existing privacypreserving aggregation query processing methods in sensor networks rely on preestablished network topology and require all nodes in the network to participate in query processing Maintaining the topology results in a large amount of energy overhead and in many cases the user is interested only in the aggregated query results of some areas in the network and thus the participation of the entire network node
