Multiple Access Protocols Channel Partitioning Random Access Protocols Taking Turns Take-Home Points Multiple Access Protocol protocol for sharing a single broadcast channel protocol determines when each node can transmit must avoid collisions collision : two or more simultaneous transmissions lead to interference so that a signal can’t be received challenge: communication about channel sharing must use the channel itself! ideal protocol for a channel of rate Rbps when one node wants to send, transmit at rate R when m nodes want to transmit, each sends at R / m fully decentralized: no master node, no clock synchronization simple to implement Multiple Access Protocols Daniel Zappala 5/18
