Abstract
εριγράφονται εκδοχές ενός μηχανισμού διασφάλισης ποιότητας υπηρεσιών για ασύρματα δίκτυα. Στις εκδοχές περιλαμβάνεται μια πολιτική ελέγχου για την αποδοχή ενός σημείου πρόσβασης ποιότητας υπηρεσιών(QAP) με στόχο τη διαχείριση του εύρους ζώνης μέσω της αποδοχής ή της άρνησης παροχής υπηρεσίας σε δέκτες ροής κυκλοφορίας σταθμών ποιότητας υπηρεσίας (QSTAs). Περιλαμβάνεται επίσης η επαναδιαπραγμάτευση διαφόρων παραμέτρων των κατηγοριών πρόσβασης στο σημείο QAP, με στόχο την ενίσχυση της απόδοσης του ασύρματου δικτύου. Μια επιπρόσθετη εκδοχή περιλαμβάνει φενός παρακολούθηση των σταθμών ποιότηταςυπηρεσιών με στόχο τη βελτιωμένη δικτύωση, ούτως ώστε νακαθορίζεται εάν το εύρος ζώνης που παρέχεται σε μία συγκεκριμένη κατηγορία πρόσβασης ικανοποιεί τις απαιτήσεις ποιότητας υπηρεσιών (QoS) υπο δικτυακές συνθήκες που μεταβάλλονται με τον χ΄ρονο κα, αφετέρου, την επαναδιαπραγμάτευση του εύρους ζώνης της δεκτής κατηγορίας πρόσβασης, εφόσον αυτό απαιτείται. Με την παρούσα εφεύρεση, επιτυγχάνεται καλύτερη διαχείριση του εύρους ζώνης, ενώ το επιπλέον κόστος για την εφαρμογή της ποιότητας υπηρεσίας σε ένα ασύρματο δίκτυο είναι πολύ μικρό. Πέραν της καλύτερης διαχείρισης του εύρους ζώνης, η παρούσα εφεύρεση αντιμετωπίζει αποτελεσματικά απρόβλεπτες πτώσεις στην επίδοση με τρόπο διαφανή για τις υπόλοιπες συσκευές του δικτύου. Επιπλέον, τα σημεία πρόσβασης και οι συσκευές client του σταθμού ενόςασύρατου δικτύου επηρεάζονται με τρόπο απόλυτα συμβατό προς τη προδιαγραφή 802.11e. Αυτά και άλλα πλεονεκτήματα των εκδοχών της παρούσας εφεύρεσης θα γίνουν περισσότερο κατανοητά με τη βοήθεια της ακόλουθης ενδελεχούς περιγραφής και των συνοδευτικών σχημάτων.
