%X Based on experiments,the paper analyzed power-exhausting process of a node in event-detection wireless sensor networks(WSN).It defined two states-dead state and alive state of a node,according to node work limitation.What is more,it proposed a detection method of node sub-death state based on heartbeat mechanism,which employs neighbor node monitoring method to detect if a node is on silent state.With the method,sub-death state was determined by voltage value and restart of a node.A formula of node death was...
