Abstract
AbstractThe Low Latency Queueing (LLQ) Algorithm is one of the popular Scheduling Algorithms that has been extensively studied in both theoretical and practical settings in Mobile Ad hoc Networks (MANETs). However, the extension of the classical M/G/1 queue in LLQ schemes in MANETs has been given little attention. Some researchers have proposed an Improved LLQ Algorithm modelled in Markov Modulated Poisson Process (MMPP)/G/1 queue system to schedule video and voice packets. In this study, we first adopt and improve on the LLQ Algorithm in the M/G/1 queue system. We study the Adopted LLQ Algorithm in MANETs under two service distributions namely; Exponential and Bounded Pareto (BP). We propose an Algorithm based on the Adopted LLQ that utilizes the technique of splitting video packets while receiving service, where one part of the video packet is transmitted along-side with the voice packets. The numerical results show that the Adopted LLQ Algorithm penalized video packets at the expense of voice packets. A comparative performance analysis of the Adopted and Proposed LLQ Algorithms under the two service distributions is carried out experimentally and the numerical results reveal that the Proposed Algorithm performs better than the Adopted in transmitting video packets.KeywordsConditional mean response timeVoiceVideo and packets
