Alejandro Cohen Asaf Cohen Muriel Medard Omer Gurewitz´ BGU BGU MIT BGU Abstract—The principal mission of Multi-Source Multicast (MSM) is to disseminate all messages from all sources in a network to all destinations. and K¨orner to more general network scenarios. Under realistic approach for time dependency of the channel, we adopt a distributed scheduling algorithm in which each user, in the beginning of each slot, estimates his channel gain and compares it to a threshold, and if exceeding it the user can transmit.
