Abstract:
Wireless broadband networks are emerging as reliable internet
access alternatives for delivery of high speed multimedia services. WiMAX is
one of such networks, designed to provide quality of service (QoS) support for
different service classes with varying QoS requirements. Scheduling algorithms
are required to provide such support. The existing scheduling algorithm uses
dynamic weight to allocate resources based on traffic loads. However, it
increases delay of real time traffics due to failure of the weight to prioritize
traffics. This paper proposes a priority load aware scheduling (PLAS) algorithm
to reduce delay in real time traffics. The PLAS algorithm introduces a priority
value to prioritize real time traffics over non-real time traffics. The algorithm was
evaluated using extensive simulations. The results show that the PLAS outperforms the existing algorithm in terms of delay
