Pre-Authentication and Selection of Suitable Target Base Station During Handover Procedure in Mobile WiMAX Network

WiMAX (Worldwide Interoperability for Microwave Access) is an emerging technology that can provide wireless broadband access at the data rates of 70 Mbps over 50 kilometres to both home and business customers. WiMAX is cost effective and offers higher data rates than other wireless networks. It supports both fixed and mobile applications. WiMAX is easier to deploy as compared to other networks and has flexible network architectures. One of the major challenges concerning the performance of Mobile WiMAX is seamless handover. IEEE 802.16e standard for Mobile WiMAX defines two kinds of soft handovers (MDHO and FBSS) and hard handover. But only hard handover mandatory in the standard and Mobile Station cannot transmit or receive data packets during this hard handover.
