Abstract
Wireless local area networks have developed into a promising solution to
support advanced data services in untethered environments. Selection of
an efficient packet-scheduling scheme is important for managing the
bandwidth while satisfying QoS requirements of active sessions having
diverse traffic characteristics. The key difficulty is the distributed
nature of the queues in the uplink, resulting in the scheduler having to
trade off polling greedy stations against wasting resources by polling
potentially idle stations. In order to address this, we propose a novel
scheduling scheme, "Embedded Round Robin", which dynamically classifies
stations as "busy" and "clear". We then extend the recently proposed
Dual Queue scheduling discipline to the case of wireless networks.
