QoE-aren optimizaziorako indize-erregelen proposamenak sare-baliabideen esleipenerako planifikazioan

Abstract

Lan honetan sakon aztertu dira erabiltzaileek hautemandako kalitatearen maximizazioa helburu duen sare-baliabideen planifikaziorako scheduling algoritmoak, beti ere sare-baliabideen esleipenean kalitate subjektiboaren maximizaziorako planifikazioaren garrantzia eta beharra buruan izanda. Ikerketak bereziki erreparatu dio matematika arloan ekarpen handia egin duten Gittins zein Whittle metodoen bidez lortutako kalitate subjektiboaren maximizaziorako scheduling indize-erregela motako soluzioen azterketei. Modu honetan, lehenik eta behin, bi diziplina horiek aurkeztu dira, Gittinsena bakunagoa izanik. Ondoren, bi planifikazio-politika horien errendimenduak elkarrekin erkatu dira, eta ikusi da Whittlen-en konponbideak emaitza nabarmenki hobeak erakusten dituela. Ondorioz, Gittins edo Whittle metodoetan oinarritutako proposamena aukeratuko da.; Considering the importance and necessity of network resource al location for maximizing subjective quality, this work deals with scheduling algorithms aimed at maximizing users’ perception of quality. This research is focused on the analysis of subjective quality aware scheduling index rule solutions obtained by means of Gittins and Whittle methods, which have a great contribution in the mathematics area. In this way, first of all, we present the previous disciplines, being the Gittins-based simpler. Then, we compare the performance of these scheduling policies, showing that the Whittle-based solution gives considerably better results. As a conclusion, a tradeoff between the index complexity and the achievable subjective qualit y exists, when choosing the Gittins-based or the Whittle-based proposal.
