Abstract:

A flexible and portable WiMAX MAC (FPWiMAC) protocol stack software system is proposed to provide a reference design for WiMAX system. By introducing an operating system (OS) abstract layer and a physical layer (PHY) management subsystem, FPWiMAC is independent to operating systems, PHY implementations and hardware platforms. System flexibility is improved by features of dynamic algorithm library, core database and so on. Moreov er, the key mechanisms, including downlink data scheduling, two-dimension data mapping, dynamic ranging region allocation, are designed to improvesystem performances. The tests show that the flexibility and portability of FPWiMAC are good. The features of high bandwidth and low latency can support the quality of service (QoS) requirements of real-time services in IEEE80216 networks.

Key words: WiMAX, media access control, protocol stack software, flexible and portable
