Radio Resource Management & Allocation In 802.16/wimax Systems
The IEEE standard 802.16 and its evolutions (i.e., 802.16- 2004, 802.16e,
802.16g) set the stage for a worldwide revolution in Broadband
Wireless Access (BWA). Also known as WiMAX (Worldwide
Interoperability for Microwave Access), IEEE 802.16-based technology
can potentially deliver fixed, portable and mobile wireless solutions
enabling high-bandwidth services with an array of multimedia
features, and it supports point-to-multipoint (PTM) and mesh network
architectures. With advantages in terms of high transmission rate and
coverage area, mobility support, and a predefined quality of service
(QoS) framework, this IP-based wireless broadband technology can be
integrated with 3G mobile networks, 802.11-based WLANs, and wire
line networks to provide seamless broadband connectivity to fixed and
mobile users. While third-generation (3G) networks are optimized
mostly for voice and data services with emphasis on mobility
capability, 802.16-2004-based WiMAX networks are optimized for
providing high peak rate multimedia services mainly for stationary
end users. Operating in the frequency band of 2–6 GHz, 802.16e can
serve the needs of fixed, nomadic, and fully mobile networks [1]
