2-hop Relay W.o.Redundancy 上浒充通大 SHANGHAI JIAO TONG UNIVERSITY Under non-cooperative mode 2-hop Relay Algorithm W.o.Redundancy I:During a timeslot,for a cell with at least two nodes: 1.If there exists a source-destination pair within the cell,randomly select such a pair.If the source has a new packet in the buffer intended for the destination,transmit.If all its destinations have received this packet,then it will delete the packet from the buffer. Otherwise,stay idle. 2.If there is no such pair,randomly assign a node as sender and independently choose another node in the cell as receiver.With equal probability,choose from the following two options: MotionCast:On the Capacity and Delay Tradeoffs 12
