METHOD FOR DETECTING FAULT OF SENSOR NETWORK BASED ON CLUSTER AND RECOVERING IT

摘要

A method for detecting error of sensor network based on a cluster for improving data reliability is provided to generate an error to a cluster head in marine sensor network in case of interruption of data transmission through a substitution node selection. A base station selects a cluster head(410). The selected cluster head is transmitted to a sensor node after selecting a substitution node according to a predetermined mode(420). The cluster head transmits a schedule to the substitution node and the sensor node(430). The cluster head check message is transmitted to its own time slot(440). The substitution node determines whether a response is received from the cluster head(450). If the response is not received from the cluster head, the substitution node transmits the error information of the cluster head to the sensor node(470).
