Sensor network system and data processing method for sensor network

InactiveUS20080031139A1Prevent overloadEnsures reliability of a sensor net systemError preventionTransmission systemsSensor nodeReal time transmission
An overload on a communication path in a sensor network system is prevented while transferring information from a sensor node as close to real time as possible. When the transfer rate of events transferred from a boundary node (DR) toward a gateway (GW) exceeds a limit transfer rate (VL), one of nodes on the sensor node (S) side whose transmission rate meets a preset condition is identified as an excess transmission rate node. The excess transmission rate node, or a node that is not the excess transmission rate node and whose transmission rate should be reduced, is chosen as a deceleration node. A node that reduces the transmission rate of events from the deceleration node, or the transfer rate of the events, is chosen as a deceleration processing executing node. The deceleration processing executing node is instructed to execute preset processing.
