Center node: "modeling analysis and impact of a long transitory phase in random access protocols"
  Abstract: In random access protocols, the service rate depends#R##N#on the number of stations with a packet buffered for transmission.#R##N#We demonstrate via numerical analysis that this state-dependent#R##N#rate along with the consideration of Poisson traffic and infinite#R##N#(or large enough to be considered infinite) buffer size may cause#R##N#a high-throughput and extremely long (in the order of hours)#R##N#transitory phase when traffic arrivals are right above the stability#R##N#limit. We also perform an experimental evaluation to provide#R##N#further insight into the characterisation of this transitory phase#R##N#of the network by analysing statistical properties of its duration.#R##N#The identification of the presence as well as the characterisation#R##N#of this behaviour is crucial to avoid misprediction, which has a#R##N#significant potential impact on network performance and optimisation.#R##N#Furthermore, we discuss practical implications of this#R##N#finding and propose a distributed and low-complexity mechanism#R##N#to keep the network operating in the high-throughput phase.
