A Bound on the Capacity of Backoff and Acknowledgement-Based Protocols
Warwick.
Work packages 2 and 4.
January 2001.
Abstract: We study contention-resolution protocols for
multiple-access channels.
We show that every backoff protocol is transient
if the arrival rate, lambda, is at least 0.42 and
that the capacity of every backoff protocol is at most 0.42.
Thus, we show that backoff protocols have (provably) smaller capacity
than full-sensing protocols.
Finally, we show that the corresponding results, with the larger
arrival bound of 0.531, also hold for every
acknowledgement-based protocol.
