Ns2 project in Greece
Ns2 project in Greece the status of the sensor is kept in the address space of the sensor’s process and is checked when the sensor is encountered during execution of the application code The resident monitor receives trace data via ns2 project in Greece event recordsgenerated by sensors. Event records contain a commandidentifier flagging the information as sensor data, a sensornumber, identifying the reporting sensor, 3 the time atwhich this event was recorded, and a sensor-specific value.Event ns2 project in Greece records are communicated to the resident monitor bynotification or by message.
