  • 1. TRAMATraffic-adaptive Medium Access Protocol By Gaurav Chauhan(121060753005)
  • 2. Overview• Introduction• Protocol Components• How It Works• Comparaison
  • 3. Introduction• Scheduled Based protocol – Distributed and on demand construction• Single channel• Nodes needs to be Time Synchronized• Time deviden into – Scheduled Access – Followed by Random Access
  • 4. Introduction(Contd…)• Broadcast and Receive the schedule/two hop neighbourhood information – Periodic Operation• So one can sleep and wake up peacefully.God bless…
  • 5. Protocol Components• Protocol Consist three subparts – Neighbourhood Protocol – Schedule Exchange Protocol – Adaptive Election Algorithm
  • 6. Protocol Components(Contd..) Neighbourhood Protocol• Executed in Random Fashion,No channel sensing,Broadcasted• Transmitted packet contains – Node`s Identification – Incremental neighborhood information • that is only those neighbor identifications are included that belong to new neighbors or neighbors that were missing during the last cycle – When a node does not transmit,it listens to pick up its neighbors’ control packets
  • 7. Protocol Components(Contd..) Schedule Exchange Protocol• Transmit its current transmission schedule – in which time slots it transmits to which neighbor• Picks up its neighbors’ schedules• Used to actually allocate slots to transmitters and receivers
  • 8. Protocol Components(Contd..) Adaptive Election Algorithm• Sometimes it is possible that there are some slots which are reserved by some nodes,but not used.• allowing nodes to reuse their neighbors’ unused winning slots• So the channel is utilized more effectively.• Afterall nobody should sit idle,either work hard or get sleep.
  • 9. Comparasion• As opposed to S-MAC, the energy savings of TRAMA depend on the load situation, while in S- MAC it depends on the duty cycle.• TDMA based have higher delays but also higher maximum throughput than contention-based protocols.• The TRAMA protocol needs significant computation and memory in dense sensor networks since the two-hop neighborhood of a node tends to be large in this case.TRAMA is a feasible solution only if the sensor nodes have sufficient resources.
