In recent times, the
demand for the real time audio and video applications in wireless networks is
very high due to widespread use of latest wireless communication technologies.
Many of these applications require different Quality of Service (QoS) in terms
of delay and throughput in the resource constrained wireless networks. In order
to handle the resources effectively and to increase the QoS, proper packet
scheduling algorithms need to be developed. Low-latency Queuing (LLQ) is a packet scheduling algorithm which
combines Strict Priority Queuing
(SPQ) to Class-Based Weighted Fair Queuing (CB-WFQ). LLQ places delay sensitive applications such
as voice and video in the SPQ and treat them preferentially over other traffic
by allowing the application to be processed and sent first from the SPQ. In this paper, an Enhanced LLQ (ELLQ) is proposed.
An additional SPQ is introduced for scheduling the video applications
separately along with the dedicated SPQ for voice applications. The performance
of the proposed algorithm is compared with other existing algorithms through
simulations using the OPNET modeler. Simulation and Statistical results show
that the proposed algorithm has given 1.5 times performance improvement in
terms of throughput and delay than the existing algorithms for the real time
audio and video applications.
