The IEEE 802.16 standard, commonly known as WiMAX, is the latest technology that has promised to offer broadband wireless access over long distance. Since 2001, WiMAX has evolved from 802.16 to 802.16d standard for fixed wireless access and to the new IEEE 802.16e standard with mobility support. With the growing popularity of WiMAX (Worldwide interoperability for Microwave Access) the security risks have increased many folds. In this paper, they will give an overview of security architecture of WiMAX. The authors propose some possible security improvements and solutions to eliminate the vulnerabilities. Finally, they will have a look at improvement reported in multi hop WiMAX networks.
