Security Problems in Mobile Wimax Networks

Mobile Wimax is a new technology which has all the feature in order to be used increasingly in the near future due to its high speed capabilities. Security for Mobile Wimax is an area that needs to be focused upon so as to protect its functionality. Mobile WiMAX systems are based on the IEEE 802.16e-2005 standards which involve a physical (PHY) layer and the medium access control (MAC) layer for broadband wireless access systems operating at frequencies below 11 GHz. A Mobile WiMax/802.16e wireless access network consists of two main entities i.e. base stations (BSs) and mobile Stations (MSs). The role of Base stations is to provide network attachment to the Mobile stations. While initiating the communication process, a MS selects that Base station which offers the strongest signal. In this approach, the subscriber plays the role of the user while a BS and a collection of served MSs play the role of system [1]. Section 2 gives the detailed information about the Security Vulnerabilities and their classification whereas Section 3 throws some light on attacks followed by the conclusion section.
