Abstract :
In this paper, we assume that the bottleneck in IEEE 802.16e networks is not necessarily the air interface but it can sometimes be the backhaul, too, since over provisioning is not always feasible. Our simulations show that applying Differentiated Services and Active Queue Management on the bottleneck links as well as taking the bottleneck link load into account in connection admission control decisions leads into more efficient use of the scarce backhaul capacity.
