Abstract
A system for reducing peak network loads in a wireless sensor network is disclosed. The system comprises a central device and a plurality of sensor apparatuses coupled to the central device. The sensor apparatuses are arranged to sense environmental events and to notify the central device when an environmental event is sensed using incidental messages. Additionally, the sensor apparatuses are arranged to notify the central device periodically in the absence of environmental events using periodic messages. The sensor apparatuses are configured to choose a transmission time T between t i,A and t i,B , for incidental messages, and between t p,A and t p, B , for periodic messages and to transmit the messages wirelessly to the central device at transmission time T, whereby at least a plurality of sensor apparatuses have transmission times which differ from each other.
