TinyCasper: A PrivacyPreserving Aggregate Location

two main modules, innetwork location anonymization and aggregate query processing over anonymized locationsInthe first module, trusted wireless sensor nodes collaborate with each other to anonymize users’ exact locations by a cloaked spatial region that satisfies a prespecified privacy requirement On the other side, the aggregate query processingqueries In this paper, we consider an aggregate location monitoring system where wireless sensor nodes are counting sensors that are only capable of detecting the number of objects within their sensing areas As traditional query processors rely on the knowledge of users’ exact locations, they cannot provide any monitoring services based on theAggregate Location Monitoring for Wireless Sensor

TinyCasper: A PrivacyPreserving Aggregate Location

This demo presents a privacypreserving aggregate location monitoring system, namely, TinyCasper, in which we can monitor moving objects in wireless sensor networks while preserving their location privacy TinyCasper consists of two main modules, innetwork location anonymization and aggregate query processing over anonymizedlocations Inthequery processing, such as pushing down predicates and minimizing communication are also important alongside ACQP and fit comfortably within its model We have designed and implemented a query processor for sensor networks that incorporates acquisitional techniques called TinyDB (for more information on TinyDB, see the TinyDB Home Page [Madden et al 2003]) TinyDB is a distributedTinyDB: An Acquisitional Query Processing System for

Aggregate Location Monitoring for Wireless Sensor

Location monitoring systems are used to detect human activities and provide monitoring services, eg, aggregate queries In this paper, we consider an aggregate location monitoring system where wireless sensor nodes are counting sensors that are only capableFor monitoring moving objects via wireless sensor networks, we introduce two aggregate query types: distinct entries to an area and the number of objects in that area We present a new technique, Distributed Euler Histograms (DEHs), to store and query aggregated moving object data Aggregate queries occur in a variety of applications rangDistributed Histograms for Processing Aggregate Data

Aggregatequery database system and processing

A processing unit can determine a first subset of a data set including data records selected based on measure values thereof The processing unit can determine an index mapping a predicate to data records associated with that predicate and approximation values of the records The processing unit can process a query against the first subset to provide a first result and a first accuracy value(ie, the state of the environment during query execution) The bounded aggregate is simply a triple: [L,A,U], where L is a lower bound, U is an upper bound, and A is the aggregate value computed over the results available in the network during the entire query execution, ie, A is an aggregate computed over the elements in the set T m i=0 E iAutomated Assessment of Aggregate Query Imprecision
