Abstract: 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.

Abstract: A method in a first network node for assisting an electronic device to benefit from a service provided by a cloud is provided. The first network node is comprised in the cloud. The first network node obtains information from the electronic device. The information comprises computation and storage capability of the electronic device. The first network node determines a push content based on the information. The first network node retrieves binary executable and content from one or more second network nodes comprised in the cloud. The binary executable and content are based on the push content. The first network node then pushes the binary executable and content to the electronic device. This is to enable the electronic device to benefit from the service of the cloud without accessing the cloud.
