A throughput optimization framework with delay constraints for backbone WMNs

Abstract

Backbone wireless mesh networking concept has been developed in order to provide higher bandwidth, better QoS (less delay and jitter) and larger coverage range compared with previous network types. These factors should be balanced in an appropriate way in order to satisfy mentioned goals. In this paper an optimization framework has been proposed in order to maximize throughput according to upper bound allowable delay. Problem has been studied in two cases with fixed and variable duration transmission intervals and results have been compared. Also secondary interference avoidance constraints based on IEEE 802.11 MAC protocol model have been discussed.
