Dynamic resource allocation with network initiated bandwidth renegotiation (DRABR) protocol for providing seamless handovers in wireless ATM networks

Abstract

With the ever-increasing demand for easy portability and mobility of devices supporting diverse mobile multimedia applications, the need for the adaptation of broadband infrastructure to the wireless scenario has arisen. Mobile multimedia networks like the wireless ATM are faced with challenges relating to user mobility management and channel access. The issue of handovers is addressed. We propose, simulate and present the relative performance appraisal of a handover strategy employing network-initiated bandwidth renegotiation and redistribution. The handover protocol is shown to perform better than static and dynamic handover schemes in terms of handoff connection drop probability.
