Secured Cost Effective Group Handover Authentication Scheme For WiMAX Networks
Technological improvement of wireless Communication is important aspect of user's daily life. Mobile WiMAX IEEE 802.16m standard aims at fulfilling the requirements on 4G Systems. Providing seamless handover authentication is a critical issue in this area. This paper proposes a grouping of mobile stations algorithm to reduce the handover latency including security considerations. In the authors' scheme the MSs which have similar Signal to Interference-plus-Noise Ratio (SINR) are grouped into the same handover group. In that MS group, while the first MS of the same handover group leaves from the Service Base Station (SBS) to target BS (tBS), the SBS transmits all the details of the handover group member's security context to the tBS.
