Abstract

In this paper, we address the issue of base station user association and resources allocation (BUA-RA) in OFDM-TDMA based broadband wireless access (BWA) networks under PON-WiMAX integration. With the powerful coordination capability at the optical line terminal (OLT), a key technology of inter-cell cooperative transmission (CT) is incorporated in the integrated network architecture, which is so called cooperative PON-WiMAX network (CPWN). To achieve efficient integration and inter-cell CT in the CPWN, BUA-RA is critical to the QoS provisioning for each user. We provide three new BUA-RA schemes aiming at minimizing the number of rejected connection requests of users' demands according to the current network resource utilization and wireless users' moving speeds. Simulations are conducted to verify the proposed BUA-RA schemes by comparing with the conventional non-cooperative transmission (NeT) approach. The results demonstrate the efficiency of the proposed BUA-RA schemes.
