Ideal multiple access protocol Broadcast channel of rate r bps 1. When one node wants to transmit it can send at rate r 2. When m nodes want to transmit, each can send at average rate r/M 3. Fully decentralized No special node to coordinate transmissions o No synchronization of clocks, slots 4. Simple 5: DatIdeal Multiple Access Protocol Broadcast channel of rate R bps 1. When one node wants to transmit, it can send at rate R. 2. When M nodes want to transmit, each can send at average rate R/M 3. Fully decentralized:  No special node to coordinate transmissions  No synchronization of clocks, slots 4. Simple 5: DataLink Layer 5-13
