Beschreibung
Zusammenfassung:	An example method includes determining, at an aggregated point in time, an aggregated space node motion amount detected in a plurality of node sensing areas of a plurality of the nodes. The determining the aggregated space node motion amount includes compiling a plurality of sensing records from a subset or all of the nodes created by the subset or all of the nodes at a time substantially close to the aggregated point in time. The method additionally includes computing a temporal aggregated motion amount detected in a node sensing area of a respective node over time, using the aggregated time node motion amount. The method further includes computing a spatial aggregated motion amount in a portion of a space, using the aggregated space node motion amount, wherein the portion of the space correlates to the node sensing areas of the plurality of nodes.
