Proposal of a Novel Bandwidth Management Framework for IEEE 802.16 Based on Aggregation

Abstract

In an environment where IEEE 802.16 access networks are used as a backbone for a heterogeneous wireless access network, the question of Quality of Service brings along a questioning on several other aspects: scalability, guarantees, scheduling among others. We give in this paper a general solution answering those questions. This solution is based on an aggregated bandwidth management in the backbone. This aggregation along with specific bandwidth request and scheduling policies are herein specified and discussed.
