Abstract:
The standard IEEE 802.11 MAC protocol uses
the Binary Exponential Backoff algorithm. The Binary
Exponential Backoff makes exponential increments to
contention window sizes. This work has studied the effect of
choosing a combination between linear, exponential and
logarithmic increments to contention windows. Results have
shown that choosing the right increment based on network
status enhances the data delivery ratio up to 37% compared
to the Binary Exponential Backoff, and up to 39 %
compared to the Pessimistic Linear Exponential Backoff
algorithms for wireless Internet.
