Abstract :
Dynamic bandwidth assignment schemes for TDMA (time division multiple access) based wireless ATM (asynchronous transfer mode) systems are discussed. TDMA generally requires hand-shake based protocols for time slot assignment which increases connection set-up time. This connection setup delay degrades the throughput performance of the wireless system if variable burst traffic, often encountered in ATM, is carried. To improve the throughput performance, this paper proposes two dynamic bandwidth assignment schemes, the autonomous assignment and release (AAR) scheme and the centralized assignment control (CAC) scheme, for TDMA-based wireless ATM and compares their throughput and delay performance
