Inventory management system using event filters for wireless sensor network data

摘要

A wireless sensor node, WSN, tag and method for filtering sensor data obtained by the WSN. At least one event filter is applied to sensor data. The sensor data is based at least in part on motion of the WSN tag. The at least one event filter includes at least one filter parameter, and the at least one filter parameter includes a minimum amount of movement of the WSN tag within a predetermined time threshold.
