Quality of service games in an IEEE 802.11 ad hoc wireless LAN
PublicationW pracy wykazano, że gdy wymaganie na minimalną przepływnośc stacji przekracza wielkość wyznaczoną przez punkt optimum w sensie Pareto, okazjonalna egoistyczna konfiguracja MAC pozwala stacjom uczestniczyć w grze typu kolejkowego, w której wypłatą jest uzyskana przepływność. Zaprezentowano przykładowe scenariusze takiej gry oraz dokonano jej analizy przy pomocy modelu gry stochastycznej, wykazując istnienie punktu równowagi oraz...
