Abstract: According to one or more embodiments of the disclosure, a device associated with a first cluster of data sources may identify an amount of data from the first cluster of data sources to be sent by the device to a satellite. The device may send, to the satellite, a request for a transmission window that indicates the amount of data to be sent by the device to the satellite. The device may receive, from the satellite, an indication of an assigned transmission window during which the device may transmit data to the satellite. The satellite may compute the assigned transmission window based on the amount of data and such that the assigned transmission window does not overlap an assigned transmission window of a neighboring device associated with a second cluster of data sources. The device may send, during the assigned transmission window, the data towards the satellite.
