Abstract

A method for managing data in a preferably non real-time sensor network, wherein the network comprises a multitude of sensor nodes to sense data, wherein the network is divided into clusters with each consisting of several sensor nodes, wherein within each cluster a sensor node acts as aggregator node to aggregate the sensed data of the rest of the sensor nodes of the cluster, and wherein always a pre-configurable number of neighbored clusters are combined to groups and the data aggregated within a cluster are stored by the aggregator node of the cluster itself and in addition by another aggregator node of a cluster of the respective group is characterized in that the data is encrypted with homomorphic methods before being stored persistently.
