Resource reservation - both just in time and advance in time - has been advocated as a means of guaranteeing quality of service(QoS) to mobile users. Often, advance bandwidth reservation results in low utilization due to bandwidth fragmentation wherein holes of unused bandwidth in time may be too small to allocate to any user yet sum of several holes may be sufficient to satisfy the user. In this paper, we introduce and investigate the problem of bandwidth fragmentation and explore different methods of minimizing bandwidth fragmentation. One is a selective call rejection scheme and the other a multi-class bandwidth sharing scheme. Through an extensive set of simulation results, we show that our proposed schemes reduces bandwidth fragmentation.
