It is disclosed a sensor system (10, 58) and a method therefore for providing quality data to a network node. The sensor system comprises two or more populations (12a, 12b, 56a, 56b) of sensors, each population having a plurality(11i, 11j, 52a, 52i, 200) of single-purpose slave sensors distributed over a geographical area and at least one master sensor(14a, 14b, 54). Based on the data quality received (302) from each single-purpose slave sensor, a master sensor may perform discretionary management (320, 322) and terminate (322) single-purpose slave sensor not meeting data quality standards. The sensor system provides a possibility to deploy master sensors and single-purpose slave sensor networks in remote or inaccessible areas without large network planning expenditures, for example by "carpet-bombing" an area with slave sensors and master sensors from the air. |
