Adaptive Probabilistic Broadcasting over Dense Wireless Ad Hoc Networks

Algorithm 1

Periodically update channel idle probability 𝑃_idle(𝑢)

based on (1).

On Backoff timer expires:

  Generate a random number 𝑝_𝑟 over [0,1]

  if 𝑝_𝑟<𝑃_idle(𝑢)

    transmit the packet

  else

    entering rebackoff

  end
