Abstract EN
In today's networks, the widespread use of real-time traffic such as video and audio applications demand special service guarantee in terms of throughput, delay, and jitter, thus making quality of service (QoS) a key problem.
IEEE 802.16 mesh networks are likely to be the basis of next-generation last mile network connectivity.
So, providing QoS is one of the major designing goals in IEEE 802.16 mesh network.
While the standard defines five service classes for PMP mode, no standard defined service classes exist for mesh mode.
In this paper, we describe a differentiated service (DiffServ) architecture for QoS support in IEEE 802.16 mesh network by considering a basic requirement for QoS guarantee—delay.
A new cross-layer routing metric is proposed, namely, expected scheduler delay (ESD).
An efficient distributed scheme is proposed to calculate ESD and route the packets using source routing mechanism.
This scheme is capable of differentiating between delay sensitive and best-effort traffic and route packets accordingly.
Finally, the results of the proposed scheme are compared with the standard schemes that take hop count as a routing metric.
