Survey on Handoff with QoS in WIMAX
Wimax stands for worldwide interoperability for microwave access. Wimax Technology that enables ubiquitous delivery of the wireless broadband service for fixed and/or for mobile users. wimax is wireless digital communication system also known as 802.16. which is intended for wireless "Metropolitan area networks" .The challenge for Broadband Wireless Access networks is in provides the Quality of Service (QoS) simultaneously to services with very different characteristics. QoS support in wireless networks is a much more difficult task than in wired networks, mainly because the characteristics of a wireless link are highly variable and unpredictable, both on a time-dependent basis and a location dependent basis.
