Multi-service traffic profiles to realise and maintain QoS guarantees in wireless LANs
This paper shows that throughput parameter \"bits/s\" does not
provide accurate insight in load conditions and/or traffic demands in
Wireless LANs (WLANs). A multi-service traffic profile that does provide
this insight is therefore defined. The multi-service traffic profile is
natural to define network resource demands for real-time applications.
Simulation results are used to show how to set the traffic profile
parameters for elastic traffic. The paper subsequently uses the
multi-service profiles to define the notion of a QoS budget. The QoS
budget is given to a terminal and the terminal can determine locally if
network consumption does not exceed the budget and whether a new network
greedy application fits within the QoS budget given. Finally, it is shown
how the QoS budget with its multi-service traffic profiles can be used to
guarantee quality of service in wireless LANs, in a situation where WLAN
channel conditions may vary in time and WLAN stations may move around
within a BSS. Simulation results found in literature are used to validate
the accuracy of the novel algorithms proposed to guarantee QoS in wireless
LANs
