  • Publication number: 20210211494
    Abstract: A method performed by a first peer node for acting as a P2P proxy for a user device is provided. The first peer node operates in a communications network. The first peer node establishes (201) a renewable energy profile of the first peer node used for powering the first peer node. The renewable energy profile indicates to what extent one or more energy sources are renewable. When a proportion of renewable energy according to the established renewable energy profile exceeds a first threshold, the first peer node acts (205) as a P2P proxy for the user device for downloading a piece of data to the user device by being powered according to its renewable energy profile.

  • Patent number: 10212492
    Abstract: A method and monitoring center (304) for supporting supervision of events in a monitored area (300) based on sensor data (D) reported by sensors over a communication network (302). When the monitoring center (304) detects an abnormal event (E), it identifies a set of sensors (S1-S3) which are potentially impacted by the event, and also identifies network nodes (N1-N3, BS) that are able to communicate sensor data reported by the identified sensors (S1-S3). The monitoring center (304) then instructs (In) the identified network nodes to promote the communication of sensor data reported by the identified sensors. Thereby, transport of the sensor data will be enhanced and it will arrive promptly and properly at the monitoring center, to enable any watching staff to take notice and evaluate the abnormal event as soon as possible.
