Abstract
This paper addresses 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 collaborative transmission (CT) is incorporated in the integrated network architecture, which is so called cooperative PON-WiMAX network (CPWN). To achieve an efficient integration and inter-cell CT in the CPWNs, BUA-RA is critical to the Quality of Service (QoS) provisioning for each user. In order to minimize the network resource usage, we provide three new BUARA schemes, which can be adaptively applied according to the network loads and wireless users’ moving speeds. Simulations are conducted to verify the proposed BUA-RA schemes by comparing with those without CT technology and to demonstrate the efficiency of the proposed mathematical formulations and linearization approach.
