Computation-Aware Data Aggregation [PDF]
, 2019 Data aggregation is a fundamental primitive in distributed computing wherein a network computes a function of every nodes\u27 input. However, while compute time is non-negligible in modern systems, standard models of distributed computing do not take ...

Location-Based Data Aggregation in 6LoWPAN
International Journal of Distributed Sensor Networks, 2015 Location-based information has recently been exploited to assist the aggregated process of data, thereby reducing the spatial redundancy efficiently. The constraints nature in 6LoWPAN becomes one of the major concerns in data aggregation methods. However,

NONPARAMETRIC ESTIMATION WITH AGGREGATED DATA [PDF]
Econometric Theory, 2002 We introduce a kernel-based estimator of the density function and regression function for data that have been grouped into family totals. We allow for a common intrafamily component but require that observations from different families be independent. We establish consistency and asymptotic normality for our procedures.
