Adapting packet fair queueing algorithms to wireless networks
Parameswaran Ramanathan, Prathima Agrawal · 1998
Bit errors are fairly common during transmission in a wireless network.As a result, a straight-forwarcl application of existing packet fair queueing (PFQ) algorithms from wire-Iine to wireless networks results in an ine~cient use of ~he Kmited wireless bandwidth.In this paper, we propose a simple approach for adapting the existing PFQ algorithms for the wire]ine networks to provide the same kind of long-term fairness guarantees while making efficient use of the wireless bandwidth.In the proposed approach, long-term fairness guarantees are provided by supplementing the bandwidth given to sessions which have not received satisfactory service in the short -t erm due to poor quahty of their wireless channel.To efficiently keep track of the amount of supplemental bandwidth for each session, the paper introduces the concept of a long-term fairness server.This concept.also allows one to easily integrate the proposed approach with any of the existing PFQ algorithms.
